A terrifying crocodile relative, with teeth like a T. rex, may have taken on dinosaursMeet "Razana," a gigantic lizard ancestor with the teeth of a T. rex and the body of a crocodile. The prehistoric beast — formally named
Razanandrongobe sakalavae — was likely a top predator in Madagascar about 170 million years ago, when dinosaurs also roamed the planet, a team of Italian and French paleontologists said Tuesday.

Tyrannosaurus rex, the scientists wrote in a study published July 4 in the journal
PeerJ. That suggests the teeth were sharp enough to slice through hard tissue such as bone and tendon.

Paleontologists said Razana appears to be by far the oldest and largest representative of a group of croc-like animals called Notosuchians. Little is known about the origin and early evolution of this group, and until now, these animals hadn't been known to exist during the Jurassic period. "Like these and other gigantic crocs from the [more recent] Cretaceous, Razana could outcompete even theropod dinosaurs at the top of the food chain," Cristiano Dal Sasso, the study's lead author and a researcher at the Natural History Museum of Milan, said in a statement.

The Razana seems to have roamed the area when Madagascar, which is now an island, was separating from the giant landmass of southern continents known as Gondwana, Simone Maganuco, a co-author of the study, said in a statement. "It represents a further signal that the Notosuchia originated in southern Gondwana," he said. WATCH: Toy dinosaurs chase real people in this ’Jurassic Park’ remake
