Meet the Carolina Butcher, a 9-Foot Crocodile That Walked On Two Legs

HughPickens.com writes Science News reports on the Carolina Butcher, a giant, bipedal reptile that looked a lot like living crocodiles — except it walked on two legs, not four. Carnufex carolinensis is one of the oldest and largest crocodile ancestors identified to date. Its size and stature also suggest that for a time, the Carolina Butcher (named for its menacing features), was one of the top predators in the part of the supercontinent Pangaea that became North America. Past fossil finds show that cousins of ancient crocodiles were vying with the earliest bipedal dinosaurs, called theropods, for the title of top predator in the southern regions of Pangaea but the Carolina Butcher's reign probably ended 201 million years ago when a mass extinction event wiped out most large, land-based predators, clearing the way for dinosaurs to fully dominate during the Jurassic period. Carnufex is one of the most primitive members of the broad category of reptiles called crocodylomorphs, encompassing the various forms of crocs that have appeared on Earth. "As one of the earliest and oldest crocodylomorphs, Carnufex was a far cry from living crocodiles. It was an agile, terrestrial predator that hunted on land," says Lindsay Zanno. "Carnufex predates the group that living crocodiles belong to." Transported back to the Triassic Period, what would a person experience upon encountering this agile, roughly three metre-long, about 1.5 metre-tall beast with a long skull and blade-like teeth? "Abject terror," says Zanno.
