These Crocs Were Made for Chewing

The video discusses the discovery of a new type of crocodile in Southern Tanzania, dating back 105 million years to the Cretaceous period. This small, terrestrial crocodile has unique features, such as forward-facing nose openings and long, slender limbs, suggesting it lived on land. Its teeth are distinct, with canine-like and molar-like structures, resembling mammalian features. The video compares this crocodile to others found in East Africa and explores its potential niche, which may have been similar to that of mammals in the northern hemisphere.
