Morrosaurus is one of the few dinosaurs known from Antarctica, showing that dinosaurs lived on every continent.1

Its leg bones suggest it was a fast runner, with a slender, tightly bunched foot that helped it sprint.1 3

Morrosaurus belonged to a group called Elasmaria, which also included dinosaurs from Patagonia and Australia, showing they shared a common land connection.3

The only known fossil is a partial right hind leg, including parts of the thigh, shin, and foot.1

It lived in a cool, temperate rainforest with high rainfall, very different from the icy Antarctica we know today.3

Léeb: Some people think dinosaurs never lived in Antarctica because it is too cold.

Dëgg: Morrosaurus and other dinosaurs lived in Antarctica when it was warmer and covered in forests, during the Late Cretaceous.1 3
