Caiuajara

O nome significa: “named after the Caiuá desert where it was found”1
Comía: PlantasRéptiles voadoresCretáceo Inferior a Cretáceo SuperiorTecnicamente non é un dinosauro

Caiuajara was a flying reptile that lived in a hot desert. It had a big crest on its head that grew steeper as it got older. Dozens of Caiuajara fossils were found together, showing they lived in colonies.1

Dato curioso: os pterosauros voaban por riba dos dinosauros, pero eran os seus curmáns, non dinosauros.

Datos curiosos

1

Caiuajara is the first pterosaur found in southern Brazil. All other Brazilian pterosaurs come from the northeast.1

2

At least 47 individuals were found in one bone bed, which is very rare for pterosaurs.1

3

Young Caiuajara had a small, slanted head crest (about 115°). Adults had a larger, steeper crest (about 90°).1

4

Caiuajara could probably fly at a very young age. This is called being precocial.1

5

It lived around an oasis lake in a Cretaceous desert. Storms may have carried dead pterosaurs into the lake.1

6

Caiuajara belongs to a group called Tapejaridae, which had no teeth and are thought to have eaten fruit.1

As preguntas máis frecuentes sobre Caiuajara

?How big was Caiuajara?

The largest Caiuajara had a wingspan of about 2.35 meters (7.7 feet). The smallest juveniles had a wingspan of about 0.65 meters (2.1 feet).13

?Did Caiuajara have teeth?

No, Caiuajara had no teeth. It belonged to a group of toothless pterosaurs called Tapejaridae.13

?What did Caiuajara eat?

Scientists think Caiuajara ate fruit, because other tapejarid pterosaurs are thought to have been frugivorous. However, no direct food remains have been found with the fossils.13

?Could Caiuajara fly?

Yes, Caiuajara could fly. Even very young individuals had well-developed flight muscles and could probably fly soon after hatching.13

?Where was Caiuajara found?

Caiuajara fossils were found in southern Brazil, near the town of Cruzeiro do Oeste in the state of Paraná. It is the first pterosaur discovered in southern Brazil.13

?Why did Caiuajara have a crest?

The crest on Caiuajara's head probably helped with display, like attracting mates or recognizing other members of its species. The crest grew larger and steeper as the animal got older.13

Caiuajara was named in 2014 by Manzig and colleagues. The fossils were found near Cruzeiro do Oeste in southern Brazil.21
Aínda en debate
Scientists are not sure exactly how old the rocks are. Caiuajara could be the youngest known tapejarid pterosaur, or the rocks might be older than thought.1
