Museum Spotlight: Fernbank Museum of Natural History

In 2006, my family and I went down to Georgia (we were lookin' for a soul to steal) to visit our really good friends the Guinees (we were way behind, and we were willing to make a deal).  On our trip, we visited what is now one of my most favorite museums of all time: the Fernbank Museum of Natural History.  While Fernbank certainly has a large number of really cool exhibits, easily my favorite one was the one around which most of the museum is built: an enormous room with a Giganotosaurus attacking an Argentinosaurus, one of the largest theropod dinosaurs known to science attacking one of the largest sauropod dinosaurs known to science.  It was simply fantastic!  In the upper levels of the atrium thing, you could also see fossil skeletons of various pterosaurs, and there was also a fossil crocodile on the ground floor!  Fantastic!

 

 

 

Another thing that I thought was really cool was a large, life-size statue of Stegosaurus outside of the museum!  Below is a picture of my sister and I acting like dinosaur in front of it!

Top 10 Favorite Dinosaurs by Zack Neher (Part 1)

Just a few days ago, we had our first ever guest blog post by David Church.  Mr. Church did his top ten favorite dinosaurs, which got me thinking about what my favorite dinosaurs were, and inspired me to do this post!  So here is my top ten favorite dinosaur list!

10. Argentinosaurus

Inhabiting South America during the Late Cretaceous Period, the enormous sauropod Argentinosaurus is the heaviest known terrestrial animal and, according to BBC, also has the record for being the longest land animal.  It was, of course, discovered in Argentina, and would have been a contemporary of Giganotosaurus.

9. Allosaurus

Allosaurus was a thirty or so foot long carnivorous dinosaur from the Late Jurassic Period.  Discovered in the Morrison Formation of Colorado, Montana, New Mexico, Oklahoma, South Dakota, Utah, and Wyoming, this dinosaur (or one quite like it) was also likely found in the Tendaguru Beds of Tanzania.  The Cleveland-Lloyd Dinosaur Quarry near Price, Utah holds the remains of more than forty individual Allosaurus bones.

8. Spinosaurus

Spinosaurus is an enormous carnivorous dinosaur that we have talked about on multiple occasions, both in our "Biggest Carnivorous Dinosaur" trilogy of posts awhile back, but also in Mr. Church's Top Ten list.  Spinosaurus, despite the fact that it is easily the largest known carnivorous dinosaur, with an estimated length of almost sixty feet, did not eat meat like the other enormous dinosaurs: instead, Spinosaurus was a piscivore, or a fish eater.  This giant creature lived in Africa during the Cretaceous Period.

 7. Parasaurolophus

Parasaurolophus is another one of those dinosaurs that overlaps from Mr. Church's list to my own.  Parasaurolophus is certainly an interesting creature!  A member of the hadrosaurs, or duck-billed dinosaurs, Parasaurolophus, as Mr. Church discussed, is the only dinosaur I know of where paleontologists know with a high degree of accuracy what they sounded like.  The large crest on the back of the head of Parasaurolophus is full of hollow tubing, similar in shape and structure to the trombone, as well as similar in sound, too.  Unfortunately, I could not find a sound file or video of the call, so if anyone has access to a scientifically reconstructed call, let me know!

The Biggest Carnivorous Dinosaur Part 1: Move Over, T-Rex (Kind Of)

Tyrannosaurus rex, the "Tyrant Lizard King," has long been a dinosaurian favorite the world over.  He is quite the interesting animal, and simply massive; the publicity received by him and the giant-sized Velociraptor in Jurassic Park helped a bit, I'm sure!  However, T-rex is no longer thought to be the largest carnivorous dinosaur.  Well, yes he is.  But he isn't.

Imagine someone who has never heard of the giraffe and elephant asks you which one is biggest.  You might say the elephant, because the elephant is much heavier and has more bulk.  But what if they mean which animal is taller?  Somewhat of a dilemma.  So using words like "biggest" (as I have done here) is not the best way to go.  So Tyrannosaurus still seems to be the heavyweight champion, there are other dinosaurs that, while more slender, were probably longer.  Kind of confusing, I know.

The fact that T-rex has some serious competition has put barely a dent into his popularity, and some of the other larger carnivores are receiving a lot of attention, too. The longest of these carnivores, which we will learn about on Wednesday, was possibly around 20% larger than Tyrannosaurus Rex!  Today, we are going to look at another enormous killer, of South American origin; the massive, the monstrous, Giganotosaurus.

Giganotosaurus is an estimated 46 feet long, comparable in length to the average Tyrannosaurus!  We do have some specimens of Tyrannosaurus that are around the same size as Giganotosaurus, but either way: Giganotosaurus was a massive animal! Of course we don't actually know for sure what the maximum size for any dinosaur is as, unlike for most living animals, we generally have a relatively small sample set, but we can make close estimates based on the finds we have.  And these estimates indicate that Giganotosaurus grew to simply massive proportions.  One of the largest terrestrial animals that we know of is Argentinosaurus (who, like Giganotosaurus, was also found in Argentina), a sauropod dinosaur that lived at the same time as Giganotosaurus.  For Giganotosaurus to prey on even the juveniles of such a large herbivore, it would similarly need to grow to massive proportions.

This pattern repeats itself all over the world, the pattern of gigantism evolving in sauropods, along with the subsequent evolution of gigantism in the theropods (meat-eating dinosaurs), is a pattern repeated throughout the world, and throughout the Jurassic and Cretaceous Periods of the Mesozoic Era, the two periods in time when the rule of the dinosaurs was absolute.  Here are some more of the predator-prey, giant-sized carnivore/giant-sized herbivore relationships seen throughout the Mesozoic.  The first animal named will be the predator, and the second will be the sauropod.

Asia, 160 MYA: Sinraptor, Mamenchisaurus
Europe, 125 MYA: Neovenator, Ornithopsis
North America, 150 MYA: Allosaurus, Diplodocus
North Africa, 95 MYA: Carcharodontosaurus, Paralititan

In tomorrows post, we will look at the last relationship, and focus on another larger (or longer) than life carnivore, Carcharodontosaurus.
