Gigantic "terror crocodiles" that were as large as buses once roamed Earth. This terrifying picture comes from study that was published this week in "Journal of Vertebrate Paleontology". The study is from universities in USA. Researchers who are experts in paleontology - study of dinosaurs - studied ancient bones found in North America. They said that dinosaurs lived along Pacific and Atlantic coasts of what is now Canada and the USA. The giant beasts preyed on other dinosaurs and were up to ten metres in length. researchers discovered that prehistoric crocodiles had razor-sharp teeth that were size of large bananas.
Co-author of study Dr Adam Cossette gave details of how he thought crocodiles lived. He said they lived between 75 and 82 million years ago and are ancestors of today's crocodiles and alligators. He wrote about his research on bone parts he studied. He said: "Until now, the complete animal was unknown. These new specimens we've examined reveal bizarre, monstrous predator with teeth size of bananas." He added that it was, " giant that must have terrorised other dinosaurs that came to water's edge to drink." Another co-author of the study described how scary beast was. She wrote: "It was so enormous, almost everything in its habitat was on menu."
