Field notes

About Cedarosaurus

What it was like

Cedarosaurus was a long-necked plant eater related to Brachiosaurus. Its front legs were longer than its back legs, so it held its neck high. Polished stones found with one skeleton may have been swallowed and kept in its gut.

Its world

It lived in the Early Cretaceous in what is now Utah and Texas. Its bones come from the Cedar Mountain and Paluxy formations. In Utah it shared the land with the big raptor Utahraptor and the armored Gastonia.

How it was found

Tidwell and colleagues named it in 1999. The type species is Cedarosaurus weiskopfae. It is named after the Cedar Mountain Formation.
