About Trinisaura
What it was like
Trinisaura was a small, two-legged plant eater from the elasmarians, a group of southern ornithopods. It is known from a partial skeleton.
Its world
It lived in 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 Morrosaurus, the armored Antarctopelta and the hunter Imperobator.
How it was found
Coria and colleagues named it in 2013. The name honors the first Argentine woman geologist to work in Antarctica.
