Tupuxuara

名字的意思： “familiar spirit, from the mythology of the Tupi people in Brazil”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Tupuxuara was a flying reptile with a huge, bony crest on its head. It soared over ancient Brazil about 112 million years ago, using its long wings and toothless beak to hunt for fish.1 2

酷東西

趣味知識

Tupuxuara had a huge crest on its head made of bone. The crest was bigger in older animals, so scientists think it was used to show off to mates.1

Its wings were very long compared to its body weight. This helped it fly well and cover long distances.1

Tupuxuara lived about 112 million years ago during the Early Cretaceous period.1

The first fossils of Tupuxuara were a snout and some wing bones. They were found in Brazil.1

There are two main species: Tupuxuara longicristatus, which had a long crest, and Tupuxuara leonardii, which had a more rounded crest.1

A third species, Tupuxuara deliradamus, was named in 2009 but many scientists now think it is not a valid species.1

Tupuxuara was a close relative of Thalassodromeus, another large pterosaur from Brazil.1

By studying its eye bones, scientists think Tupuxuara was active during the day.1

關於 Tupuxuara 最常被問的問題

?How big was Tupuxuara?

Tupuxuara had a wingspan of about 4.7 metres (15.4 feet) and weighed around 25 kilograms (55.1 pounds). Its body length was about 2 metres (6.6 feet).1

?What did Tupuxuara eat?

Scientists think Tupuxuara was probably a terrestrial omnivore or carnivore, eating a mix of plants and small animals. Earlier ideas that it ate only fish or fruit are less likely now.1

?Did Tupuxuara have teeth?

No, Tupuxuara had a toothless beak, like many other pterosaurs from its group.1

?Why did Tupuxuara have a crest?

The large bony crest on its head was probably used to show off to mates, since it grew bigger as the animal got older. It was a sign of sexual maturity.1

?When did Tupuxuara live?

Tupuxuara lived about 112 million years ago, during the Early Cretaceous period.1

?Is Tupuxuara a dinosaur?

No, Tupuxuara is a pterosaur, which is a flying reptile. Pterosaurs are not dinosaurs, though they lived at the same time.1

迷思破解王

迷思： Some people think Tupuxuara was a dinosaur.

真相： Tupuxuara was a pterosaur, a flying reptile that lived at the same time as dinosaurs but is not a dinosaur.1
