Crocodile ancestor was top predator before dinosaurs roamed North America | EurekAlert! Science News - http://www.eurekalert.org/pub_rel...
"A newly discovered crocodilian ancestor may have filled one of North America's top predator roles before dinosaurs arrived on the continent. Carnufex carolinensis, or the "Carolina Butcher," was a 9-foot long, land-dwelling crocodylomorph that walked on its hind legs and likely preyed upon smaller inhabitants of North Carolina ecosystems such as armored reptiles and early mammal relatives." - rønin
