About Pelorosaurus

What it was like

Pelorosaurus was a large sauropod, a long-necked plant eater related to Brachiosaurus. It is known mainly from a large upper arm bone. Many other bones have been placed in it over the years, which makes its size hard to judge.

Its world

It lived in the Early Cretaceous, in what is now England. It comes from the Tunbridge Wells Sand, where it shared the land with Iguanodon and the armored Hylaeosaurus and Polacanthus.

How it was found

Mantell named Pelorosaurus in 1850. The type species is Pelorosaurus conybeari. It was the first sauropod recognized as a land animal rather than a sea creature.
