Interesting, on several levels...

We were talking just the other day about the South's giant prehistoric crocodile, Deionosuchus, which has lived in the Late Cretaceous some 80 million years ago. Deinosuchus, which reached lengths of 30 feet and weighed perhaps 8 or 9 tons, was first discovered in North Carolina but has been found across the southern states.

An analysis of petrified feces has revealed that the big guy may have had a sweet tooth for dinosaurs. Paleontologist David Schwimmer (more on that later) from THE Ohio State University and his grad student Samantha Harrell recently presented results at a meeting of the Geological Society of America in which they discussed evidence from bite marks on dinosaur fossils and from coprolites (that's fossilized poop, for the uninitiated) that they feel link Deinosuchus to attacks on relatively large dinosaurs. One potential prey was a T. rex relative known as Appalachiosaurus montgomeriensis, discovered near Montgomery. In addition, Harrell has analyzed coprolites indentified as belonging to Deinosuchus and discovered that they contain sand and shell fragments, indicating that the big crocs lived in shallow, brackish environments that likely contained an abundance of their preferred prey - sea turtles.

So, now for the more intriguing fact. David Schwimmer, OSU paleontologist really does exist. It's not some sort of weird Friends alternative reality. Really.
