About Puertasaurus

What it was like

Puertasaurus was a titanosaur, one of the biggest long-necked plant eaters. It is known from only a few huge backbones, so its size is a rough estimate, around 30 meters (98 feet) long.

One of its back bones is extremely wide, which suggests a very broad, deep chest.

Its world

It lived in the Late Cretaceous, about 84 to 72 million years ago, in what is now southern Argentina. Its bones come from the Cerro Fortaleza Formation, the same rocks that held the giant titanosaur Dreadnoughtus and the small plant eater Talenkauen.

How it was found

Novas and colleagues named Puertasaurus in 2005. Only one find is known.
