About Berthasaura
What it was like
Berthasaura was a small theropod with a toothless beak. That is unusual for its group, and it suggests the animal may have eaten plants or a mixed diet. It is known from a nearly complete skeleton, probably of a young animal.
Its world
It lived in the Cretaceous in what is now Brazil. Its bones come from the Goio-Erê Formation, a desert of sand dunes where it lived alongside the small predator Vespersaurus.
How it was found
De Souza and colleagues named Berthasaura in 2021. The name honors a Brazilian scientist and campaigner for women's rights.
