The Denver Gem and Mineral Show Part 1: Giant Ammonites, Burrowing Amphibians and Leaping Lizards

On Sunday, the 16th, my friend Masaki Kleinkopf and I visited the Denver Gem and Mineral Show at the Denver Merchandise Mart.  It was a ton of fun!  They had booths from all over the place, like the Morrison Natural History Museum and the Rocky Mountain Dinosaur Resource Center, an excellent dinosaur museum up in Woodland Park near Colorado Springs!  One of the most exciting things by far was when a pair of women came up to us, and asked if they could film us just going about our business.  They were part of a group making a movie under the working title "Quarry."  It's apparently going to be about American Paleontology, and it looks like Masaki and I may have made the part about why Americans love paleontology, and especially dinosaurs, so much!

MESSAGE FROM ZACK FROM THE FUTURE:  Hello, everyone.  This is Zack Neher.  I have travelled to this post from the future.  I wanted to give you a link to the Homebase for these posts.  I am like Rose Tyler, leaving clues in the form of Bad Wolf.  Except this is not quite like that at all really.  Anyways.  The Homebase for the series is HERE.
Creeper shot of the film crew following us, with a large iridescent ammonite in the foreground.  Notice the distinct chambers.  How magnificent.

We also saw Dr. Robert Bakker there.  After I said hello, he waved me over and said "You're a smart kid.  Can you tell me where the nostrils are on this thing?"  The "thing" that he was referring to was a baby Eryops skeleton that he has been working on, a Permian amphibian that lived in the south eastern United States.  Remains have been discovered in both Texas and New Mexico, and it was a contemporary of Dimetrodon, who most likely preyed upon it.  Upon my examination, I promptly tried to prove his assessment of my intelligence wrong, as I pointed all over the skull in my attempts to locate the nostrils.  Turns out, the nostrils were right where they should be.  They were just confusing because in life, the animal would have been able to cover the nostrils with little flaps of bone, sealing off the nostrils from dirt and such while it was burrowing.  Pretty interesting stuff!
Dr. Bakker's baby Eryops.  The snout is facing the pen in the left of the image, and the two holes that you can see are the orbitals, or the eye sockets.  The googly eyes are explained below.
Another picture from a few weeks ago.  This was taken at the Morrison Museum when my friend Kristie Chua came up to visit.  Dr. Bakker, when asked "Why the googly eyes?"  replied "I put the googly eyes on because I like it." 

We also saw a number of giant ammonites.  Below are a few pictures of the better ones, probably the largest I have ever seen!  The only other possible contender that I can think of was one that I saw at the Heritage Museum of the Texas Hill Country in (you guessed it!) Texas.  That one was a huge, probably five or six feet wide, imprint of an ammonite, right outside the entrance to the museum.  This was the same place that I have talked about before, in my Acrocanthosaurus on the Prowl post.  Great place!  I definitely recommend checking it out if you are ever in the Canyon Lake/San Antonio area of Texas!
The Heritage Museum ammonite.  Perhaps my memory is a bit off.  But I still remember it being incredibly, enormously large.  Perhaps the picture makes it looks smaller?  A mystery.  I suppose I will have to check it next time we go back there now won't I.
The ammonites, in order of amazingness.  Probably about a two, two and a half foot diameter.
Although its size was less impressive, perhaps only a foot or two wide at the most, it was most amazingly iridescent.  There were a large number of them here, but somehow I succeeded in capturing zero great pictures.  Go figure. 
Same story as above.  Not as impressive in size, but amazing in preservation quality.  Check out those septum!
Masaki next to one big ass ammonite! 
And Masaki with another big ass one!  This one a bigger ass!  Bigger ass one?  Bigger one.  A bigger one.
The third really cool thing that we saw there (that I am going to include in this post, at least) were these preserved lizards.  These lizards are from the genus Draco, and are found exclusively in Indonesia.  These lizards are remarkable as they can glide from tree to tree.  Many paleontologists and biologists speculate that this is what the earliest Pterosaurs would have looked like.  For those of you who don't know, Pterosaurs are the flying reptiles that were contemporaneous with the dinosaurs.  Often confused with the dinosaurs themselves, the Pterosaurs were distinct in that they were truly flying reptiles, and not a distinct grouping.  Calling Pterosaurs dinosaurs would be akin to calling a tiger salamander a mammal, on the sole observation that the tiger salamander is a contemporary of a squirrel.  Not so.
One specimen of the Draco lizards....
....and another!
Famous examples of Pterosaurs include (or "Pterosaurs That I Have Heard Of):

  1. Anurognathus
  2. Darwinopterus
  3. Dimorphodon
  4. Dsungaripterus
  5. Eopteranodon
  6. Eudimorphodon
  7. Hatzegopteryx
  8. Ornithocheirus
  9. Peteinosaurus
  10. Pteranodon
  11. Pterodactylus
  12. Pterodaustro
  13. Quetzalcoatlus
  14. Rhamphorhynchus
  15. Sordes
  16. Tapejara
  17. Tropeognathus
You probably also know the Pterosaurs as the "Pterodactyls."  Probably should have prefaced with that.
A skull of Darwinopterus from the show.  This guy was at the booth for the Rocky Mountain Dinosaur Resource Center, or RMDRC for short, an awesome museum up in Woodland Park.  
The wing of a good sized Pterosaur.  You can see at the bottom of the picture a white round thingy.  That's the ammonite featured in the picture with Masaki, above.  That should help give you an idea of the scale of the wing.  Probably around ten feet or so.  And get this; that whole thing is one enormously elongated pinky!
A fossil pterosaur from the show
Another fossil pterosaur from the show
Anyways, in the Imax production "Flying Monsters" with David Attenborough (FAVORITE.  IMAX.  EVER.), they talk about how many scientists speculate that these lizards of the genus Draco greatly resemble the earliest ancestors of the Pterosaurs.  Initially gliding from tree to tree to snatch flying insects in the air, eventually these small lizards would have become capable of powered flight.  Then, they would have grown larger and larger, until they became the biggest animals to ever take to the skies.  Except for humans, but really.  We don't really count.

War of the Wombats

There are three different types of wombat.  There is the common wombat (Vombatus ursinus), the southern hairy-nosed (Lasiorhinus latifrons) and the northern hairy-nosed (L. krefftii).  They have been classified by the IUCN, respectively, as Least Concern, Least Concern, and Critically Endangered.  Unfortunately, all three wombats face threats that could easily result in their extermination from the wilds of the earth.  Fortunately, steps are being taken to prevent such a wombacide.

In Queensland, Australia  lies Epping Forest National Park.  In just two square miles of this park live the last ninety individuals of the northern hairy-nosed wombat.  Surrounding this puny area is a 20 kilometer long perimeter fence, erected after 10 wombats were killed by dingoes a few years ago, which, considering the severity of a ten percent population loss in such a small population, makes total sense.

Although these steps are being taken to protect the northern hairy-nosed, this species of wombat still faces several severe problems.  One such problem is the fact that 75% of these wombats are male, making a boom in their population more difficult to achieve.  Fortunately for the northerners, the southern hairy-nosed wombat has a very similar reproductive system as the northern hairy-nosed.  Scientists are therefore using female southerners as surrogate mothers for the northerners.  This method is referred to as "cross fostering," and has been used successfully when it comes to other marsupials.

The other major problem confronting the northern hairy-nosers is the fact that all of the animals are located in the same place.  In the event of a disease, wild-fire, or some other similar catastrophe, most or all of these creatures could be exterminated in the virtual blink of an eye.  Conservationists think it wise to create a second population of northerners, not too far away from the first, but far enough away to ensure that a disaster could not take out both populations with one fell swoop.  Scientists and conservationists have decided that it would be most beneficial to the northerners if they were to assist in their burrow construction.

These burrows, which can be over 100 feet long, would be time-consuming construction projects.  Not only that, but a single wombat will often use up to five different burrows, moving to a different one each day.  The first wombat doesn't just leave his or her old burrow unoccupied, however, as another wombat, probably the same one every five days or so (I would guess), temporarily moves in.  It's really less of a permanent residence, like a house, and more of a time-share condo.

But just how time and energy consuming would it be to dig such a burrow if you were a wombat?  Wombats have a problem with keeping cool.  If you ask my opinion, I suspect it has a lot to do with their body design.  As we discussed a few posts ago, animals that live in hot environments typically adapt in ways to increase their Surface Area to Volume ratio, or SA:V for short.  To learn more about why this is, click HERE.  However, fossorial, or burrowing, animals, like the wombat, aardvark, marsupial mole, and many, many others, try to keep their bodies streamlined.  Like dolphins and sharks, these animals want to be able to glide smoothly through their desired area (be it water or burrows).  Having random chunks of body, i.e. the ears of an elephant or a deer, would merely slow the animal down.  That is my theory, anyways.

To keep cool in the heat of the Australian day, wombats will take refuge in their burrows.  However, to be efficient enough when it comes to trapping moisture (as water can often be very difficult to come by in the habitat of the northerns), it has been estimated that the burrow would need to exceed fifteen feet in length.  It has also been calculated that the approximate amount of energy required for a wombat to dig a three foot long chunk of burrow is about the amount of energy that a wombat would expend running twelve miles.  That means for the comforting fifteen foot length of burrow, the wombat could instead run about sixty miles.  Clearly no small effort.

The way that the scientists actually figured all of this out was really quite interesting.  To see how long it takes for a wombat to dig a burrow, experimenters Glen Shimmin and David Taggart put one wombat into a box.  (Equipped with breathing holes, of course.  As pirates and I like to say, "A dead wombat digs no holes").  The human duo then dug a hole in the ground the same size as the box.  Placing the wombat-infested box into the ground, they then opened up one end of the container, allowing the wombat free access to the soil.  Instinctively, the wombat would begin to dig.  A half an hour later, Shimmin and Taggart ceased the wombat-excavation, and carefully measured how much dirt was displaced by the wombat, as all of the displaced dirt would conveniently be shoved (by the wombat) into the box!  Convenient, huh?  During the half hour digging session, the wombat moved more than 100 pounds of dirt!  Impressive, but the team concluded that, if conservationists were to release a group of northern hairy-nosed wombats into their new territory without pre-dug burrows, it was incredibly likely that the wombats would simply dig themselves to exhaustion, and subsequent death.  An undesirable outcome for all parties involved, it was decided to dig man-made burrows, resembling those of wombats, throughout the habitat, prior to the installation of the wombat center-piece.

What are some other problems facing wombats?  Well for starters, some of these problems, even when facing the wombats in the face, are virtually invisible to them.  Wombats, like Stegosaurus, rhinos, and myself (without my contacts), are virtually blind.  You don't need eyes if you are a fossorial (burrowing) creature; just ask the marsupial mole, the golden mole, or many other types of fossorial animals who no longer use, or even have, eyes!  However, when it comes to crossing roads, their terrible eyesight really takes its toll.  Hundreds, if not thousands, are hit by cars each year.

Other problems include starvation, drought, mange, and other people problems.  Starvation can be easily caused by the gradual squeezing out of the native grasses typically consumed by wombats by other, inedible grasses.  Drought should be self-explanatory; without water, the food dies.  Without water, there is no water.  Both are not good for wombats.  Mange, for wombats at least, is a fatal skin disease.  And as for the other people problems?  Let's just say that prairie dogs can relate.  (And now, even though I just said "Let's just say," I am going to go into more detail).  Like prairie dogs, wombats burrow.  And also like prairie dogs, the habitat of the wombat is perfect for ranchers.  So it goes like this.  Ranchers come along, and bring their cattle.  The cattle step in prairie dog/wombat holes, break their legs, and die.  The ranchers, enraged, take their rage out on the culprits: the prairie dogs or the wombats.  And as we have discussed before, wombat burrows can be quite extensive.  Furthermore, the entrance holes would have to be quite fat in order to accomodate such...robust occupants. 

As we have also previously discussed, much is being done in order to protect the wombat.  Another bit of good news is that a population boom of around 10% was recorded for the sole population of the northern hairy-nosed wombat!  Another wee bit of hope in a world that we willfully wish not to become wombatless.

WOMBAT FACTS:

  1. Cooling Off:  Besides retreating into their burrows, wombats will also flick dirt onto their bodies to keep cool.
  2. Olympic Runners:  Despite its dumpy appearance, the wombat can reach a top speed of around 25 mph.  This means that it can outrun an Olympic sprinter, like Usain Bolt!
  3. Cooling Off V 2.0:  Besides retreating into their burrows and flicking dirt onto their bodies, wombats are also nocturnal, meaning that they avoid the heat of the day.
  4. Life Span:  Wombats can live around twenty years.
  5. Wombat Wesearch:  Prior to around fifteen or so years ago, not much research had been done on wombats.  Most of what we know has been discovered since that time.
  6. Power House Excavators:  For their size, wombats may be the world's most powerful excavators.

Thieving Penguins

Adélie penguins are quite interesting little fellows.  One interesting aspect of the Adélie penguins that we are going to look at today is their trickiness and thievery.

Penguins are popular animals and, with the possible exception of the emperor penguin, the Adélie is probably the most famous.  In his excellent book "Penguins:  Past and Present, Here and There," mammalian paleontologist and penguinologist George Gaylord Simpson says, "Pygoscelis adeliae has probably figured in more cartoons than any other creature except Homo sapiens."  This, in my opinion, and I believe his, too, is due to the fact that they seem so very human.  But looks aren't the only similarities that humans have with the Adélie; it appears that the Adélie penguin partakes in thievery, as well!  But if you don't believe me, you don't have to take my word for it!  Take the word of David Attenborough, in this clip from BBC's Frozen Planet, below! 

https://www.youtube.com/watch?v=qhiG6_83pbc

The Adélie penguin is labeled "Near Threatened" by the IUCN, and lives throughout Antarctica.  Their two closest relatives, and fellow members of the genus "Pygoscelis," are the "Least Concern" gentoo (P. papua) and the "Near Threatened" chinstrap (P. antarcticus) penguins, seen below.
Finally, I would like to apologize for my lack of posts in the last couple of weeks!  What with school, the upcoming lecture, volunteering at the Morrison Museum, and watching every single episode of Psych (GREAT SHOW) in order, I have a lot going on, despite what my parents seem to think!

23 Fact Tuesdays: Ceratosaurus, Octopi, Aye-aye, and More!

Introducing:  23 Fact Tuesdays!  I'm thinking that (possibly) each week, we can look at twenty-three different groups of....things....and we can learn a fun fact about them each week!  Many of these topics feature North America, as that is where both I and most of my readers reside, but other topics include penguins, fossil horses, fossil mammals, early humans, various fish and birds, dinosaurs, and many more!
Here they are!

Don't want to read all twenty-three!  Well, in my opinion, the best ones are 10, 14, 15, 17, 18, and 19!  Enjoy!

1.  Alaskan Mammals:  The Sitka black-tailed deer will graze on beach plants like dune grass and kelp during the lean season.

2.  Alaskan Fish:  The whitefish may fast for eight or nine months during the lean season, surviving off of their stored fat.

3.  Dinosaurs:  In 1883, Ceratosaurus was the first large meat eating, or Theropod, dinosaur skeleton that was discovered more than half complete.  The first skeleton was discovered in Colorado.

4.  Dinosaurian Contemporaries:  Lagosuchus was either the direct ancestor, or a close relative of the ancestor, of the dinosaurs.

5.  North American Birds of Prey:  The robin-sized American Kestrel is not only the smallest hawk in North America, but it is also the most common.

6.  Tideland Treasures of South Carolina:  The palmetto, which is the state tree of South Carolina, can live for 75 years, and grow to a height of 60 feet, with a 1 or 2 foot diameter.

7.  North American Mammals:  The least chipmunk, besides eating the usual rodent foods like nuts, will also dine on insects, and occasionally small vertebrates.

8.  North American Hoofed and Marine Mammals:  The sperm whale is the largest of the toothed whales.

9.  North American Birds:  The common goldeneye will often take over abandoned woodpecker nests.

10.  Fossil Mammals:  Despite the fact that primates no longer live in North America, many paleontologists think that they either evolved there or in Asia.

11.  Penguins:  Despite the fact that most people think of penguins living in cold, snowy climates, the king penguin typically forms colonies in the shelter of dense tussock grass.

12.  Fossil Horses:  One species of Hypohippus, H. osborni, had weak and infrequently used side toes.  Although not very exciting sounding, this is an important step from multi-toed horse ancestors to the one-toed horses that we know today. 

13.  Dinosaurs....Again!:  Ornithomimus, one of the "ostrich-dinosaurs," lived both in the states of Colorado and Montana, but also in the country of Tibet.

14.  Extreme Abilities:  In order to protect itself from various predators and to hunt its various prey, the amazing Indo-Malayan octopus can mimic an enormous variety of different animals, including flounder, sea snakes, crinoids, jellyfish, lionfish, hermit crabs, stingrays, brittlestars, stomatopods, and sea anemones, amongst many others.

15.  Extreme Movement:  Although this dude looks like a worm or something, the caecilian is actually a close relative of newts and salamanders.  It lives strictly underground, and is rarely seen, despite the fact that they can grow up to five feet long.

16.  Extreme Growth:  The ostrich is a serious record breaker amongst birds.  Not only does it when the tallest bird and heaviest bird awards, but it also is the fastest runner, has the biggest egg, and has the largest eyes.  In fact, the smallest bird on the planet, the tiny little bee hummingbird, could easily fit inside the eye of the ostrich!

 17.  Extreme Families:  The "Biggest Nest of Any Bird" Award goes to the orange-footed megapode, or the scrubfowl.  Although these nests are just on the ground (the biggest nests in trees are built by bald eagles), they are still very, very impressive.  On average, these nests can be 11.5 feet wide and 39 feet tall!  The biggest ever recorded, however, was a whopping 164 feet wide!

18.   Remarkable Mammals:  The aye-aye, possibly one of the creepiest looking animals in the natural world, is a type of lemur whose large incisor teeth grow continuously.

19.  Remarkable Birds:  Once thought to be the missing link between reptiles and birds, the South American Hoatzin hatches out of its egg with claws on its wing greatly resembling those of the ancient Late Jurassic bird Archaeopteryx.  These wing claws are not often, and maybe even never, found on birds today, with the obvious exception of the baby Hoatzin.  As the Hoatzin grows, its wing claws disappear.  

20.  Remarkable Fish:  The electric eel can discharge fifty volts from its body.

21.  Remarkable Reptiles and Amphibians:  The Cuban tree boa will position itself in small apertures in caves, striking with deadly accuracy at bats that fly out of the cave.  Remarkably, the snake will do this in complete darkness, somehow sensing where the bats are.

22.  Prehistoric Animals:  Like Lagosuchus, Effigia is another possible relative of the dinosaurs.

23.  The Evolution of Humans:  Homo heidelbergensis is thought to have been the last common ancestor between the Neanderthals (Homo neanderthalensis) and us humans, Homo sapiens

Cryolophosaurus: The Dinosaur in the Freezer

When you looked at that picture, you probably didn't think much of the background.  You probably just glanced at the dinosaur.  Well take a closer look at that background.  Where do you think it is?  I'll give you a hint.  This is what that area looks like today:

If you guessed Antarctica, then you are 100% correct!  During the Mesozoic Era, or the time of the dinosaurs, Antarctica was a very different looking place.  It would definitely have been a bit nippy at times, but nowhere near as cold as it is today, and was more of a cool temperate biome!  Cryolophosaurus, meaning "Cold Crest Lizard" in Latin (and also the dinosaur in the first picture above), lived during the Early Jurassic Period, more than 180 million years ago.  As you can see on the map below, the world looked quite different than it does today! 

Interestingly, Cryolophosaurus was originally called "Elvisaurus," named such for the small crest that it has on its head, and its similarity to the swoop of hair that Elvis had on his own head.  I don't know why they changed the name, but if you ask me, Elvisaurus is a better name all around!

The inspiration for this post came from something that I saw Dr. Thomas Holtz, a famous paleontologist, share on Facebook the other day regarding Cryolophosaurus.  It was an incredibly interesting reconstruction, but I am not sure how factually based it is, given the dubious nature of the placement of the dinosaur.  Last I had heard, Cryolophosaurus was outside the given range of dinosaurs that had feathers, so I believe that it might have just been an artistic liberty on the part of the author!  Regardless, it was pretty cool looking, and I wanted to share!

Penguin Party: The Korora and the Magellanic

Today's post is devoted to two of the seventeen (debatably a lower number) of the extant penguin species, the Korora (commonly known as the little blue penguin, the blue penguin, the little penguin, or the fairy penguin), and the Magellanic penguin.  What's the connection with these two penguins?  Well, not really anything, except for the fact that we had just talked about the Korora in a post a few weeks ago, and I had found a few funny videos of both the Korora and the Magellanic! 

The Korora is actually believed to be fairly closely related to the Magellanic penguin, compared to most of the rest of the penguins.  Despite the differences in their genus (the Magellanic belongs to the genus "Spheniscus" and the Korora to the genus "Eudyptula,") most scientists believe that the Eudyptula penguins (only one extant, but likely extinct ones) were the last ones to diverge from the Spheniscus genus. 

As we talked about a few weeks back, the Korora is labeled as "Least Concern" by the IUCN, and inhaibts Australia and New Zealand, as well as a few other random islands in the vicinity.  Interestingly enough, the Korora has also been reported in Chile and South Africa, although the probability of these animals being vagrants (essentially, lost) is quite high.  However, most penguinologists are certain that many populations of penguins started out as vagrants, so who knows!  It is how they would get from one place to another. 

The Penguin Parade (see below) is a major tourist attraction.

HERE is a link to a clip talking a bit about the Penguin Parade.  The clip talks a bit about the work done by the rangers and scientists regarding the Korora, including ranger Ashley Belsar.  For over thirty years, since 1968, this research team has been recording information about the penguins as they come ashore.  An interesting statistic that I learned from this video is that the average penguin spends about 80% of its life in the ocean!

And for those of you who want something a bit more"cutesie," HERE is a video of Cookie, the Korora, being tickled by humans at the Cincinnati Zoo in Ohio!

Native to the South American countries of Chile, Argentina, and occasionally Brazil, the Magellanic penguin is one of four of the Spheniscus genus of penguins, including the African, Humboldt and Galápagos penguins.  Labeled as "Near Threatened" by the IUCN, somewhere in the neighborhood of 40,000 of these penguins are killed each year by oil spills, which has resulted in their decreased IUCN status.

Next, we have two amusing Magellanic penguin videos.  The FIRST is of a Magellanic on a plane, and the SECOND is a trio of Magellanics who accidentally knock over the camera that is filming them.  Enjoy!

Now, we have a few really cute pictures of some of the Magellanic penguins from Sea World: Orlando in Florida!  The second two photos are from a publicity thing where some people from Sea World: Orlando brought some Magellanics to the Star newsroom!  How cute!

Birds of Prey on Marshall Road

Today, my friend Mona Kamath and I went out to find some birds of prey along a little side road off of Marshall Road between Boulder and Superior in Colorado.  We saw an abundance of them on this trip, perhaps more than on any other trip.  The only other trips that I can remember that could rival this one were one where I saw red-tailed hawks, kestrels, and turkey vultures, and another one where I saw red-tailed hawks, turkey vultures, and a golden eagle.

Today, we were rewarded with not one, but two golden eagles!  Below are some pictures taken by both me and Mona.

 
 
 
 
We also saw a number of turkey vultures circling overhead, and a pair of them perched on a fence nearby.  However, by far the most exciting vulture spot of the day was when a juvenile turkey vulture landed right behind us!  I stopped the car and Mona was able to snap a few pics.  Not quite as exciting as the time a few weeks ago when I was on this road, and saw a pair of turkey vultures and a bunch of magpies fighting over the remains of a small carcasses, maybe thirty feet from my car!  Note how similar the juvenile turkey vulture looks compared to black vulture adults.
 
I also saw a bird of prey perched upon a lamp post in the middle of Superior.  I don't know what kind it is, so if anyone can help me out with that, that would be awesome!  Anyways, here are a few pics of it:
 
 
One of my most favorite bird of prey moments on this road was perhaps a month or two ago when I saw a pair of hawks flying along calmly next to each other, and then they suddenly locked talons.  I'm not positive, but I believe that it might have been a courtship display!

The Sounds of Star Wars

The dog that was once owned by George Lucas has gone down in history in more ways than one.  One very famous example stems from the dogs name: Indiana.  This inspired the first name of the swashbuckling adventure hero "Indiana Jones" from the film franchise of the same name.  Another very important legacy of Indiana (the dog) stems more from appearance.  Apparently, the idea for Chewbacca, the lovable Wookiee from the Star Wars franchise, came to Lucas when he saw Indiana sitting up in the passenger seat of Lucas's own car!  In fact, the name "Chewbacca" apparently is derived from the Russian and Ukrainian word "собака," which means dog.

Ben Burtt, the sound editor for all six Star Wars movies, recorded a number of bear sounds for the purpose of creating Chewbacca's speech.  Along with bears, cats such as the lion and the mountain lion were also recorded.  Camels were used in addition to these fiercer companions.  These were by no means the only contributions by the animal world to the sounds of Star Wars, however!  For example, when it came to the patrons in the Mos Eisley Cantina in Episode IV: A New Hope, many different tactics were utilized.  Synthesized Latin and chopped-up Swahili served for two of the customers, but animals were used as well.  One patron's laughter stemmed from a hippopotamus, while anothers came from a spring peeper tree frog.

That's not all when it comes to the Cantina scene, however!  Ponda Baba was the Aqualish alien, below, who, along with his friend Dr. Evazan, picked a fight with Luke Skywalker and Ben Kenobi.  He was "voiced" by a walrus.  Meanwhile, besides "dogs growling and bats squeaking," the "laughter" of hyenas was also used for the laughter of some of the Cantina's other patrons. 


Here are some more sounds, and what kind of animals contributed to their creation:

Geonosians:  Here is what Matthew Wood, the actor who brought the voice of the famous and much-loved General Grievous to life, has to say regarding the sounds made by the Geonosians:

"I recorded the mating calls of penguins as they came back from the Antarctic to little Phillip Island in Melbourne.  Other sounds came from when I was up in the rain forest; I was in a flying fox area, and they let me get close to these two flying foxes.  One of them had a banana, but the other one wanted some of it, so they started fighting.  They were really mad, and I recorded that whole thing.  So, for the Geonosians, Ben [Burtt] combined mating penguins and fruit bats fighting over a banana."

The penguins that he is referring to are the korora, commonly called the little blue penguins, discussed in a recent post.  They would also not have been returning "from the Antarctic," as these birds, the smallest known penguin, past or present, are not cold-weather birds, and really stick pretty close to Australia.

Boga:  One of my absolute favorite characters (yes, I know, technically she is just an animal, but still) was voiced by a combination of one of my favorite REAL animals, the Tasmanian devil, along with a few yelps from dogs and coyotes.

Wampa scream: An elephant bellow, overlied by the squawk of a sea lion.

Mynocks:  The whinny of a horse played backwards at half the normal speed, beginning with the bark of a seal.

Ugnaughts:  The noises made by these pig-like aliens were primarily from the pups of an arctic fox, as well as the mother, but a bit of "raccoons in a bathtub" was mixed in.

Rancor Noises:  The dachshund owned by the neighbors of Ben Burtt, the Syllas, barking, growling, and hissing.

The Sando Aqua Monster:  The deep growls that this massive creature from Episode I: The Phantom Menace makes were actually from the throat of Burtt's then-three month old daughter, named Emma.  "At one point, she had a growl in her voice when she was crying.  I thought, I can use this!  So I recorded that and then lowered the pitch way down in the computer."

 Kaadu:  The snorts of the kaadu were recorded from the sounds a whale made out of its blowhole when surfacing at San Diego's Marine World.

Kaadu/Gamorrean Guard:  Both of these creatures (the grunts of the kaadu, and everything for the Gamorrean Guard) were recorded from pigs.  Unsurprising, at least for the Gamorrean, given his appearance!

Poggle the Lesser - The leader of the geonosians (that is, until Queen Karina the Great is revealed in season two of the Clone Wars) was voiced in a number of different ways, but partially through "Swahili-type vocal clicks."

Acklay:  This creatures noises and shrieks were created from reworked dolphin noises, as well as a few pig sounds.

Octuparra Droids:  The sounds from these massive droids from the Clone Wars were partially created by cows.

Gor:  Pet of the aforementioned General Grievous, Gor was voiced by a mixture of a lion and a vulture.

Gundark:  This creature, first mentioned in the original trilogy ("You look strong enough to pull the ears off a gundark," said Han Solo to Luke Skywalker after his traumatic ordeal at the hands [haha irony (because the wampa gets his hands cut off)] of the wampa) was created from a conglomerate of a horse and a shrieking parrot.

I have to say, I think one of the coolest places to visit would be Skywalker Sound, the place where all of the sound and stuff for the Star Wars movies and tons of other movies are made, organized, edited, and such.  If they gave tours, then I would totally make the trip out there!  To take a tour of Skywalker Ranch would be absolutely fantastic!

Perfume-Loving Lions and Record-Breaking Cheetahs

Two interesting pieces of feline-news for you today!  The first actually takes place at the Denver Zoo!

13 year old male lion named Krueger seems to really like "Obsession," by Calvin Klein!  Apparently, if the perfume (or is it cologne?  Man-fume?) is sprayed inside of his enclosure, he goes to the same spot and "rubs his cheek on it."  When you actually think about it, it totally makes sense.  Perfumes and colognes are supposed to attract people due to pheromones inside of them.  Animals also use pheromones, mostly to communicate.

Has a cat ever done this to you?  Scent glands in the cheeks of cats (as well as in their paws) contain pheromones, used in communication.  Each cat has a unique scent, and it rubs off when they rub into things like this.  So when your cat greets you, it is partly due to affection, and also partly due to the fact that they are really marking you as their territory.  At least they aren't peeing on you!  So this explains why Krueger would rub his cheeks against the spots of Obsession sprayed around his enclosure.

Interestingly, the lions seem to enjoy Obsession more than other perfumes, and not all of the lions were attracted to it: only half of them were, in fact!  Emily Insalaco, an employee at the Denver Zoo, thinks that the lions like this particular cologne more than others due to the presence of cinnamon, which the lions have seemed partial to in the past.  If you want to see a video containing more information, click below.

Fun Fact:  If America didn't attack Japan with atomic bombs in World War II, the Japanese might have come under siege by bat.


Although I originally thought this to be a hoax, it certainly appears as if this is real.  I have found information on it on multiple sources.  And it is actually a brilliant plan too!  Here is what happened:
 On December 7th, 1941, the Japanese attacked Pearl Harbor in Hawaii, bringing the United States into World War II.  When Pennsylvanian dentist Lytle S. Adams heard the news on the radio, he thought back to his trip to New Mexico's Carlsbad Caverns, and their extensive bat population.  He then thought up his idea for the "bat bomb:" strapping small, incendiary devices to thousands, perhaps millions, of bats, and releasing them over a strategic city in Japan.  The bats, as they would anywhere else in the world, would try to find cover in buildings, trees, and whatever nooks and crannies they could find before daybreak.  Then they would ignite the incendiary devices.  "Think of thousands of fires breaking out simultaneously over a circle of forty miles in diameter for every bomb dropped," he said.  Luckily for Adams, he knew Eleanor Roosevelt, and contacted her with his idea.  The White House actually liked it.  Said a Presidential memorandum: "This man is not a nut. It sounds like a perfectly wild idea but is worth looking into."  
Now, animal rights activists, beware.  Obviously, this plan is not very kind to the animals, and involves all sorts of animal cruelty.  To get the bats shipped, they forced them into a hibernation by sticking them into ice cube trays.  Next, the bats would be loaded into what essentially looked like a bomb-shell, consisting of 26 trays, with each of the trays containing compartments that would hold 40 bats.  Dropped from 5,000 feet, parachutes would deploy at 1,000 feet, all while the bats were awakening from their hibernation.  They would then fly off and roost, and then set the city on fire when the time was right.
Bats were the ideal creatures for this project, too.  They are nocturnal, so the Japanese would be hard-pressed to figure out what was going on.  They occur in simply massive numbers, so obtaining a great deal of them would not be super problematic.  In many caves, bats occur in the millions.  Furthermore, when bats are hibernating, they require no food, and therefore need little care when it comes to cleaning up little messes.  And finally, and perhaps most importantly, bats can carry more than what they weigh in flight, making them the perfect candidates for carrying bombs.  
The plan was to send 10 B-24 bombers, each with around 100 shells chock-full of bats, would fly from Alaska, and release around 1,040,000 bats over the cities of Osaka Bay, such as Osaka, Amagasaki, Hannan, Kobe, Sakai, and Nishinomiya.  However, the weapon experienced a few changes of hand, most notably to the hands of the Navy in August 1943, following an incident near Carlsbad, New Mexico, where bats were accidentally released.  They roosted under a fuel tank, and set fire to Carlsbad Army Airfield Auxiliary Air Base.
The project was ultimately canned in 1944, when it was learned that the bat-bomb project would likely not be operational until about halfway through 1945.  It seems likely that the atomic bomb is what caused the projects termination, even after an estimated $2 million was spent on it.  But who knows?  Perhaps this is REALLY what is going on at Area 51.

Shrinky Dink: The Channel Island Fox and The Island Effect

If you (as a species) get trapped on an island, there is really one of three things that can happen.  The first thing, which seems to be like it would be the most common of the three things, is that you and your species would go extinct on the island.  Perhaps your species still survives on the mainland, but the island group has died off.  The second, and second most likely to happen (in my opinion) is you and your species, over many generations, shrink, to match the food supply.  If there is a limited supply of food, then the smallest of your species, not the largest, are much more likely to survive.  And the third happenstance is that you and your species grow in size over many generations.  Say you and your species are rats.  On the mainland, you are preyed upon by dogs, foxes, coyotes, cats, and the like.  When you and other of your rat buddies became trapped on the island, there was an abundnace of food there, but no predators to prevent you from growing bigger.  So grow you did.  We will talk about a very interesting occurrence of this later on. This shrinking and growing, called "Foster's Rule," is often simply known as "The Island Rule."

For now, however, we are going to focus on the more common of the two, and the more interesting (both in my opinion); island dwarfism.  This has occurred many, many times throughout history, and even to humans!  However, today we are going to look at one particular occurrence of this dwarfism.  The Channel Island fox of the Channel Islands off of the coast of California.

Scientists believed that the ancestors of these foxes "rafted" to the northernmost islands in the island chain sometime between 10,400 and 16,00 years ago.  These ancestors would have been the gray fox, very similar to the ones we see today.  The foxes rafted over during the last Ice Age.  This would have dramatically lowered the sea levels, and much of the water that is in today's oceans would be locked away in the ice caps at the poles, or in glaciers.

As you can see in the map below, the four islands of San Miguel, Santa Rosa, Santa Cruz, and Anacapa are all located with only shallow water separating them.  During the Ice Age, with the lower sea levels, these four islands were all one island, called Santa Rosae.  Also at this time, the distance from the mainland to the "mega-island" would be much smaller, making the crossing for these gray foxes much easier.  It has been theorized that Native Americans then brought the fox to the four southern islands, as hunting dogs, or perhaps even pets.

Today, the fox only lives on six of the eight islands, with distinct sub-species on each island.  The fox still inhabits the islands of San Miguel, Santa Rosa, Santa Cruz, San Nicolas, San Clemente, and Santa Catalina (often simply called Catalina Island), and is absent from the islands of Anacapa and Santa Barbara.  While Santa Barbara is too small to support the food needs of the fox, Anacapa has no consistent source of fresh water.  The fox is the largest on Catalina, and the smallest on Santa Cruz.  The foxes on the southern three islands all have become separate at different dates, with the foxes of San Clemente estimated as being the oldest (becoming isolated between 3,400 and 4,300 years ago).  The San Nicolas fox is next, at around 2,200 years ago.  Finally, the foxes of Catalina Island, between 800 and 3,800 years ago.

Even smaller than the mainland kit and swift foxes, the Channel Island is the smallest of all of North America's foxes.  Like many island animals, the Channel Island fox is labeled as "Critically Endangered" by the IUCN, as they don't have much territory to spread into when humans influence them.  One influence was indirect, but still devastating for the foxes.  Prior to the 1990s, the golden eagle was a rare visitor to these islands.  The bald eagle, already well established in the area, was apparently a large deterrent for the golden eagle, preventing them from settling on the island.  DDT helped to eradicate the bald eagle on the Channel Islands, and with very few bald eagles in the area, the golden eagle moved into the gap: nature abhors a vacuum!

Anyways, the golden eagle, unlike the bald eagle (who is primarily piscivorous) would, and did, hunt the Channel Island foxes; at four times the foxes size, they were most definitely a force to be reckoned with.  That, coupled with diseases brought over from the mainland by domestic dogs, such as canine distemper, have also wreaked havoc upon the fox populations.  Conservationists are currently working on a solution, and tracking the foxes with radio collars seems to be helping them learn more about the foxes, in an attempt to prepare for the future.

Guards of the Fairy Penguin

In the summer of 2009, a number of brutal attacks in Sydney, Australia left nine victims dead.  According to BBC, “the mutilated bodies...were found in a national park near Sydney harbour.”  Autopsies performed on the bodies reveal that the murderers were most likely foxes, although dogs remain a definite suspect.

There is more to this story than has been revealed thus far.  The nine victims were not humans; instead, they were korora, or little blue penguins, also often called fairy penguins. You would be excused for thinking that the victims were, in fact, humans, especially once you learned the whole story.

In an interview with BBC, Sally Barnes of the New South Wales Parks and Wildlife Service detailed what the group has been doing to protect the penguins from the dogs and foxes.  As well as raising public awareness, the NPWS has been baiting and trapping the predators, and “As a last resort, we’ve also had shooters out.” 

In this case, shooters means snipers.  That’s right; the Parks and Wildlife Service deployed two professional sharpshooters in order to ensure the safety of these penguins.  Armed with night-vision goggles, rifles, and orders to shoot to kill, these may be the most extreme methods used to protect penguins ever employed. 
The penguins are being further protected by vigilantes from the Manly Environment Centre, vowing that they will do “whatever it takes” to protect the penguins, and planning on assisting the snipers in keeping a sharp eye on the birds 24/7. 

Why is this colony such a big deal?  The kororaa is labeled as “Least Concern” by the IUCN.  Well that may be true for the total population of korora, but this colony is falling by the wayside.  As you can see in the map, the area where the colony is located is quite busy, and not ideal penguin habitat.  However, these penguins cannot be relocated; like many birds, they always return to where they themselves were raised to come ashore and raise their own chicks.  The people of Sydney also take pride in their colony of korora’s, as it is the sole population located in New South Wales.  The people at the Manly Environment Centre report that their efforts are, by and large, successful, and the korora’s numbers are on the rise.
