About Tyrannotitan
What it was like
Tyrannotitan was one of the largest meat eaters of its time, about 13 meters (43 feet) long. It belonged to the same family as Giganotosaurus and Carcharodontosaurus, huge hunters with long skulls and blade-like teeth.
It is known from parts of the skull, backbone, hips and legs of two animals.
Its world
It lived in the Early Cretaceous in what is now Argentina. Its bones come from the Cerro Barcino Formation, where it shared the land with the giant titanosaur Patagotitan and the long-necked Chubutisaurus. Big plant eaters like these may have been its prey.
How it was found
Novas and colleagues named Tyrannotitan in 2005. Two finds are known.
