酷東西

趣味知識

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

?How big was Berthasaura?

About 1 metre (3.3 ft) long. It was a small theropod.3 1

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.3 1

?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.3 1

?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.3 1

?Is Berthasaura a dinosaur?

Yes, it is a dinosaur. It belongs to a group called ceratosaurian theropods.3

?When did Berthasaura live?

During the Cretaceous Period, about 121 to 72 million years ago.3
