Fossil shows crocs outdid dinosaurs
A fossil of a new marine crocodile species found in Brazil shows the reptiles survived the extinction of dinosaurs 65 million years ago, researchers say.
Brazilian paleontologists said the discovery of the fossil of the 10-foot-long Guarinisuchus munizi, dubbed “Sea Warrior,” also engendered a new theory on the migration of prehistoric crocodiles from Africa to South and then North America.
The 62-million-year-old fossil, described in the Proceedings of Royal Society B research journal, is part of the Dyrosauridae group, which replaced mosasaurs, or serpentine marine lizards, as the dominant marine predators in the Paleocene epoch.
