Volgatitan

What it was like

Volgatitan was a long-necked, four-legged plant eater known only from tail bones. It was first described as a titanosaur, but later study suggests it may be a relative of Mamenchisaurus instead.

Its world

It lived in the Early Cretaceous in what is now western Russia, near the river it was named after.

How it was found
