Crocodiles may think so.
A crocodile descended from a former dinosaur predator?
Paleontologists found fossils in the Grand Staircase-Escalante National Monument in southern Utah that proves that ancient crocodiles used to eat dinosaurs. Clint Boyd and his colleagues Stephanie Drumheller and Terry Gatesrecently published a study in PLOS ONE detailing the bit marks of a crocodyliform on the 75-million-year-old fossils of three juvenile hypsilophodontid, small two-legged herbivores.
This proves that dinosaurs had to be wary of predators as soon as they hatched, according to NBC News. The researchers do not yet know how large the crcodyliform that made the teeth marks was, but the three dinosaurs it bit were probably between 28 and 46 pounds. Crocs today that are three to size feet long can consume animals about that size. Scary.
