About Chubutisaurus
What it was like
Chubutisaurus was a large long-necked plant eater, known from part of a skeleton. It may have reached about 23 meters (75 feet) long, though estimates vary.
It belonged to the same wide group of sauropods as the titanosaurs, but outside them.
Its world
It lived in the 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 big hunter Tyrannotitan.
How it was found
Del Corro named Chubutisaurus in 1975, from a single find. Teeth of a large hunter were found with the bones, so its body may have been scavenged.
