Field notes

About Morrosaurus

What it was like

Morrosaurus was a small, two-legged plant eater from a group of southern ornithopods called elasmarians. It is known only from a hind leg, which shows it was probably a quick runner.

Its world

It lived about 72 to 66 million years ago, at the end of the Late Cretaceous, in Antarctica. The land was forested and much warmer than today. Its bones come from the Snow Hill Island Formation, and other dinosaurs from the region include the plant eater Trinisaura, the armored Antarctopelta and the hunter Imperobator.

How it was found

Rozadilla and colleagues named it in 2016 from one find. The type species is Morrosaurus antarcticus.
