Pteranodon

名字的意思： “winged toothless”1

吃：魚飛行爬蟲類白堊紀晚期嚴格來說不是恐龍

Pteranodon was a huge flying reptile that soared over an ancient sea. It had a big crest on its head and no teeth, but it caught fish with its long beak.1

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

Pteranodon was not a dinosaur, but a flying reptile called a pterosaur.1

Males had a huge, backward-pointing crest on their skull, while females had a smaller crest.1

It lived during the Late Cretaceous, about 88 to 80 million years ago.1

Pteranodon flew over the Western Interior Seaway, a shallow sea that split North America in two.1

More than 1,100 specimens of Pteranodon have been found, making it one of the best-known pterosaurs.2

Its wings were made of skin stretched between a long fourth finger and its body.1

關於 Pteranodon 最常被問的問題

?How big was Pteranodon?

Adult male Pteranodon had a wingspan of 5.6 to 7.6 metres (18 to 25 feet), while females averaged about 3.8 metres (12 feet). A large specimen of P. longiceps is estimated to have weighed about 50 kilograms (110 pounds).1

?Did Pteranodon have teeth?

No, Pteranodon had no teeth. Its name means 'wing without tooth' because its beak was toothless, similar to modern birds.1

?What did Pteranodon eat?

Pteranodon ate fish. Fossilized fish bones have been found in its stomach area, and a fish bolus was found between the jaws of one specimen.1

?Could Pteranodon fly?

Yes, Pteranodon was a flying reptile. Its wings were thin membranes of skin stretched from its arms to its ankles, supported by a very long fourth finger.1 4

?Why did Pteranodon have a crest?

The crest was probably used for display, especially in males, who had much larger crests than females. It may have helped them attract mates or recognize each other.1

?Is Pteranodon a dinosaur?

No, Pteranodon is not a dinosaur. It is a pterosaur, a flying reptile that lived at the same time as dinosaurs but belongs to a different group.1

?When did Pteranodon live?

Pteranodon lived during the Late Cretaceous period, about 88 to 80 million years ago.1

?Where did Pteranodon live?

Pteranodon lived in North America, especially over the Western Interior Seaway, a shallow sea that covered parts of what are now Kansas, Nebraska, Wyoming, South Dakota, and Alabama.1

?How many Pteranodon fossils have been found?

More than 1,200 specimens of Pteranodon have been found, making it the best-known pterosaur.1

?Was Pteranodon bigger than a plane?

No, Pteranodon was much smaller than a plane. Its wingspan was up to 7.6 metres (25 feet), which is about the length of a small car, not a plane.1

迷思破解王

迷思： Pteranodon is often called a dinosaur.

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