Metriorhynchids, Crocodiles of the Sea

Galvasean

Is it just me or does the term 'hypercarnivore' seem a bit underwhelming when you realise a hypercarnivore's diet can consist of as little as 70% meat?

Geosaurus and Dakosaurus swam in the same seas, likely because each targeted different prey. Dakosaurus, with its T. rex-like skull and teeth, would have been able to feed on large marine reptiles, fish and cephalopods. Geosaurus, on the other hand, had a streamlined body and a lighter skull. Its teeth were better at slicing through soft bodied, fleshy prey.

Andrea Cau of the University of Bologna's Giovanni Capellini Geological Museum told Discovery News, "This study opens a new and unexpected perspective on the evolution and paleoecology of these marine predators."
