An interdisciplinary team of specialists has revealed a large, hypercarnivorous crocodile that lived in southern Argentina about 70 million years ago.

Spinosaurid dinosaurs were able to develop up to three generations of teeth at the same time, a high replacement rate that explains why so many teeth of this type have been found in Cretaceous sites.

But why was Majungasaurus so different from other carnivores? Previous work on theropod dinosaurs focused on the famous tyrannosaurs which replaced their teeth slowly.
