Cearadactylus

名字的意思： “Ceará finger, from the Brazilian state Ceará and Greek daktylos, finger”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Cearadactylus was a big flying reptile that soared over ancient seas about 112 million years ago. It used its long jaws and many teeth to catch slippery fish. Even though it could fly, it was not a dinosaur, but a pterosaur.1 2

趣味小知識：翼龍在恐龍頭上飛來飛去，但牠們是恐龍的親戚，不是恐龍喔。

酷東西

趣味知識

The first skull found was 57 centimeters long, about as long as a baseball bat.1

Scientists think it had about 16 to 18 teeth in its upper jaw and 11 to 13 in its lower jaw on each side.1

Its name means 'Ceará finger', because pterosaurs have a long wing finger that supports their wings.1

The first fossil was damaged and put together wrong, making the head look upside down. Later, scientists fixed it.1

It lived near the coast and probably flew over the ocean to catch fish.2

Some scientists think Cearadactylus might actually be the same animal as another pterosaur called Brasileodactylus.1

關於 Cearadactylus 最常被問的問題

?How big was Cearadactylus?

Its wingspan was about 4 meters (13 ft), and it weighed maybe 15 kilograms (33 lb). Another scientist estimated a wingspan of 5.5 meters (18 ft).1

?What did Cearadactylus eat?

It ate fish. Its long jaws and interlocking teeth helped it keep hold of slippery fish.1

?Did Cearadactylus have a crest?

Yes, after the fossil was fixed, scientists saw a crest on its snout.1

?When did Cearadactylus live?

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

?Was Cearadactylus a dinosaur?

No, it was a pterosaur, a flying reptile, not a dinosaur.1

?Is Cearadactylus the same as Brasileodactylus?

Some scientists think so. A 2025 study found Cearadactylus might actually be the same animal as Brasileodactylus.1

迷思破解王

迷思： People sometimes think Cearadactylus was a dinosaur.

真相： It was a pterosaur, a flying reptile that is a close cousin of dinosaurs, but not a dinosaur.1
