Magnapaulia

What it was like

Magnapaulia was a very large duck-billed dinosaur from the branch of hadrosaurs that bore hollow crests on their heads. It had tall spines along its tail, which made the tail deep from top to bottom.

It ranks among the largest members of its group, although only a few partial skeletons are known.

Its world

It lived about 84 to 72 million years ago, in the Late Cretaceous, in what is now northwestern Mexico. Its bones come from the El Gallo Formation.

How it was found

Its bones were first described as a possible species of Lambeosaurus. Prieto-Marquez and colleagues gave it a genus of its own in 2012.
