Ancient crocodile fossil found in Chatham
Scientists at N.C. State University and the N.C. Museum of Natural Sciences have discovered an ancestor of crocodiles that likely was a dominant predator in what is now North America before the age of dinosaurs, according to a report published Thursday in the open access journal Scientific Reports.
Posted — Updated"This guy was pretty big. I probably would have been the right size for lunch," N.C. State graduate student Susan Drymala said Thursday. "There’s plenty of scary things out there today, but nothing this big."
Paleontologists from the museum and N.C. State found the fossils in 2004 in a rock quarry in Chatham County. They date to the beginning of the Late Triassic Period, which was about 231 million years ago, when what is now North Carolina was a wet, warm equatorial region beginning to break apart from the super-continent Pangea.
"Originally, they were in a boulder about the size of a Volkswagen," museum curator Vincent Schneider said. "So, it took three to four days in the field to actually remove the specimens from the boulder because we had to cut them out with a rock saw."
Schneider brought the fossils back to the museum, where they remains a mystery for several years.
"We knew they were some kind of early Triassic vertebrate," he said.
Drymala, who was then studying Triassic animals, began investigating the bones, and she and Zanno were able to identify the fossils as parts of a skull, spine and upper forelimb.
"It’s a significant find. It’s not like a whole animal, but there was enoigh there to actually determine the relationships between it and other crocodilian-like animals,” Schneider said.
"It definitely was one of the biggest things for its time. Its skull was at least a foot and a half (long)," Drymala said.
