Fun facts
Berthasaura is the first toothless meat-eating dinosaur relative found in Brazil.1
Its skeleton was nearly complete, making it the most complete non-bird dinosaur from the Brazilian Cretaceous.1
Berthasaura lived about 121 to 72 million years ago, during the Cretaceous Period.2
It had a short, deep jaw and a downturned beak, similar to some plant-eating dinosaurs.1
Even though it was young when it died, Berthasaura already had no teeth, so it probably never grew any.1
Berthasaura is a noasaurid, a group of small, lightly built dinosaurs that are relatives of the bigger abelisaurids.1
Most asked questions about Berthasaura
?What did Berthasaura eat?
It probably ate plants or was an omnivore. Because it had no teeth and a beak like a bird, scientists think it was not a meat eater like many of its relatives.31
?Did Berthasaura have teeth?
No, it had a toothless beak. Even though it was a young dinosaur when it died, it already had no teeth, so it probably never grew any.31
?Where did Berthasaura live?
In what is now southern Brazil, in a desert environment. Its fossils were found in the Goio-Erê Formation in Paraná State.31
?Is Berthasaura a dinosaur?
Yes, it is a dinosaur. It belongs to a group called ceratosaurian theropods.3
?When did Berthasaura live?
