Crocodiles, some of the most vicious predators in our planet's history, are known for their size and power. How big did crocodiles get? In this video, Vividen explores how prehistoric crocodyliformes like Sarcosuchus, Deinosuchus, and Purussaurus approached tyrannosaur-level size and what that could mean for the theoretically biggest crocodiles of all time.
