About Paraxenisaurus

What it was like

Paraxenisaurus was an ostrich-like dinosaur from the same family as the giant Deinocheirus. It is known from a few bones of the tail, hips, hands and feet, so its size and shape are uncertain.

Its world

It lived in the Late Cretaceous in what is now Mexico. Its bones come from the Cerro del Pueblo Formation, a coastal land shared with the crested duckbills Velafrons and Tlatolophus.

How it was found

Serrano-Brañas and colleagues named it in 2020 from one find. The type species is Paraxenisaurus normalensis. It was the first member of its family found in North America.
