Jurassic jaws: how ancient crocodiles flourished during the age of the dinosaurs
New research has revealed the hidden past of crocodiles, showing for the first time how these fierce reptiles evolved and survived in a dinosaur dominated world. While most modern crocodiles live in freshwater habitats and feed on mammals and fish, their ancient relatives were extremely diverse - with some built for running around like dogs on land and others adapting to life in the open ocean, imitating the feeding behaviour of today's killer whales. Research published today [11 September] in the journal Proceedings of the Royal Society B shows, for the first time, how the jaws of ancient crocodiles evolved to enable these animals to survive in vastly different environments, all whilst living alongside the dinosaurs 235 to 65 million years ago. The study was conducted by Tom Stubbs and Dr Emily Rayfield from the University of Bristol, together with Dr Stephanie Pierce from The Royal Veterinary College and Dr Phil Anderson from Duke University. Tom Stubbs, who led the research at the University of Bristol, said: "The ancestors of today's crocodiles have a fascinating history that is relatively unknown compared to their dinosaur counterparts. They were very different creatures to the ones we are familiar with today, much more diverse and, as this research shows, their ability to adapt was quite remarkable. "Their evolution and anatomical variation during the Mesozoic Era was exceptional.
