Snowy Palms: An Omen of Death

Recently, parts of Southern California experienced some surprisingly cold weather, as falling snow graced the tops of the palm trees around Christmas time.  A White Christmas is nothing terribly surprising for folks like myself, born and raised in Colorado, but for California natives it was definitely more of a surprise.  People had pulled over on the side of the highway for an opportunity to play in the snow, throwing snowballs and taking selfies all over the place.

A family stopped along Interstate-15 in Temecula, California to play in the snow, a scene that could easily have been lifted out of Colorado, if not for the trees adorned with green leaves, and especially the palm tree in the background.

Although the winter freeze was very exciting for many of the residents, for the native residents of Southern California's deserts, the freeze would be much less welcome.  Over millions of years, the animals that call these seemingly barren slopes home have evolved to cope with extreme environmental stress typical of those experienced in the desert.  Aridity and extreme heat of course play major roles in any desert ecosystem, and many of the adaptations of desert animals are in response to these climatic factors.
The bobcat (Lynx rufus), one of the residents of the Southern California deserts.  This particular individual was at The Living Desert in Palm Desert.
A captive desert bighorn sheep (Ovis canadensis nelsoni) at The Living Desert.  This subspecies is native to the southern United States and Mexico.
A western diamondback rattlesnake (Crotalus atrox), also native to the southern United States and northern Mexico.
A wild greater roadrunner (Geococcyx californianus) that I chased through a Target parking lot.  
A wild California ground squirrel (Spermophilus beecheyi) that we saw foraging around at The Living Desert.
A hummingbird, possibly an Anna's hummingbird (Calypte anna).  Hummingbirds in Colorado will fly south for the winter, in order to avoid harsh weather like that seen in Southern California last week,
Of course, environmental conditions that fall well outside the norm are arguably equally important for animals native to a specific biome or region.  Even if a population of animals thrives in the harsh, arid landscape of Southern California, if all it takes is a single night of snow to wipe out the population, unusual weather (such as that seen in the area last week) can be extremely troublesome.  Extreme weather can also help control populations, and can be what keeps other animals from colonizing an area.  For example, if a population of desert rodent attempts to colonize the mountains around Palm Desert, but is unable to cope with the occasional snow storm, then that type of rodent would be much less likely to survive and thrive there.

Pictures of my Animals From My New Camera!

For Christmas I got a new camera, a Canon EOS Rebel! I have a ton of awesome pictures that I want to share, including pictures of my pets, some astrophotography, and more!  First, I am going to share some pictures of some of my various critters!  To see some higher quality versions of some of these pictures, check out my Flickr by clicking HERE!  First off, some shots of my beagle-basset dog, Daisy!
My mom with Daisy!
Next up are some pictures of my chubby kitty, Chimney!
Up next are some of my other pets, such as Juan Priestly the betta fish!  I have two, a delta tail and a veil tail, and I can't remember for certain which one is which.
In another tank I have two African dwarf frogs (Hymenochirus boettgeri), and this is the new one I got just a few days ago!  I named after the bright star Aldebaran in the Zodiac constellation of Taurus the Bull!
In the same tank, I also have a snail.  Petco (where the pets go) says that it is a gold Inca snail (Pomacea bridgesii).  However, that scientific name seems connected to a snail that is colloquially called the mystery snail, so I'm not entirely certain what this snail is.  So I suppose the name "mystery snail" truly does seem appropriate!  Anyways, I named him Liam, after Liam Payne in the fantastic band One Direction.  This is what I do to people I like, I name snails after them.  Maybe next time I will upload a picture of my other snail, Zayn Malik.
Second to last, here is a picture of Wolverine, my baby California kingsnake!
Finally, here is a picture of someone who is not my pet, and is actually a pet of some friends of mine, Isabel and Sam Lippincott!  This is their dog Louis, who was actually attacked by a coyote.  He is fine now, and is going to make a full recovery!

Proterosuchus....or Should I Say "Broterosuchus?"

Before we learn about Proterosuchus, it will be helpful to discuss where this creature comes from.  Proterosuchus is an archosaur, and to understand what an archosaur is, we must first travel back 320 million years into Earth's history: back....to the middle of the Carboniferous Period.  To travel back to that period of Earth's history, click HERE TO SEE A POST I JUST MADE ABOUT THE EVOLUTION OF THE ANIMALS THAT WE ARE TALKING ABOUT RIGHT NOW.  Unless, of course, you are fine with just accepting the idea that the archosaurs are relatives of the dinosaurs, pterosaurs, and crocodilians, in which case you can just skip that post.  I think it's interesting, though, so it might be worth checking out!

Well, that was confusing.  So how does all of this evolutionary rig-a-ma-roll pertain to Proterosuchus?  Well, in his excellent book entitled "Gorgon," paleontologist Peter D. Ward actually talks about that.  Here is that passage from his book:

"During the Triassic a whole new suite of vertebrates populated the land.  The oldest true "ruling reptiles," the stock that would ultimately give rise to the dinosaurs, are found in the oldest rocks of the Triassic.  The most ancient of these is Proterosuchus.  Yet within several million years, there was a variety of these predinosaurs, belonging to a group known as the archosaurs.  From these ancestral stocks the successful lines of crocodiles and crocodile-like animals known as phytosaurs evolved.  From other members of this group came lizards, snakes, and, by the middle of the Triassic, the first true dinosaurs."  

Well, that certainly sums it up quite nicely, don't you think!  Anyways, Proterosuchus was around the size of the extant Komodo dragon, and was one of the largest reptiles alive during its time, in the Early Triassic Period.  Similar in appearance to the modern day crocodiles, it has been theorized that this animal would lie in wait much like the crocodilians, ambushing its prey when it came down to bodies of water to drink.  One bit of evidence that causes some scientists to believe that Proterosuchus hunted like the crocodilians was that the eyes of Proterosuchus were were located on top of its head, again like the crocodilians.

Remains of Proterosuchus are known from both China and South Africa, where it was first discovered by Robert Broom, a famous South African paleontologist, in 1903.  This specimen was discovered in the Karoo Basin, an enormous desert in South Africa where large numbers of fossils have been discovered.
