【】The prehistoric beast -- formally named

Meet "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.。

Although the ancient lizard's body was long and lean like that of a modern crocodile, Razana was made even more beastly by its deep skull shape and powerful straight limbs, the fossils indicated.。Mashable Light SpeedWant more out-of-this world tech, space and science stories?Mashable Light SpeedWant more out-of-this world tech, space and science stories?Sign up for Mashable's weekly Light Speed newsletter.。

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 Madagascar fossils are thought to predate other forms of the Notosuchia by 42 million years, according to the study. 。

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.。
