名字的意思： “Hao's wing, named after Professor Hao Yichun”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Haopterus was a flying reptile that lived about 124 million years ago. It had a long, pointed snout full of sharp teeth, and it probably soared over the sea to catch fish.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。

趣味知識

Haopterus was the first pterosaur fossil from China to preserve a complete skull.1 2

Its skull was about 14.5 centimeters (5.7 inches) long, and it had 12 pairs of teeth in both the upper and lower jaws.1

The first three pairs of teeth in the front of its mouth were very small, and scientists think they might have been newly erupted replacement teeth.1

Haopterus had a fan-shaped breastbone with a strong keel, which helped anchor the muscles for flying.1

Its hind legs were weak, and its foot bones were very short, so scientists think it walked on all fours when on the ground.1

The fossil was found in 1998 at the Sihetun locality, and the rock layer was dated to 124.6 million years old.1

關於 Haopterus 最常被問的問題

?How big was Haopterus?

Its wingspan was about 1.35 metres (4.43 feet). Its skull was 14.5 centimetres (5.7 inches) long.1

?What did Haopterus eat?

It probably ate fish. Scientists think it was a piscivore, meaning it caught fish while soaring over the sea.1

?Did Haopterus have a crest on its head?

No, it did not. Its skull was low and lacked a crest.1

迷思破解王

迷思： Haopterus was a dinosaur because it lived with dinosaurs.

真相： Haopterus was a pterosaur, a flying reptile that is not a dinosaur.1

發現: Haopterus was named by Wang Xiaolin and Lü Junchang in 2001. The fossil, found in 1998 at Sihetun in China, was the first Chinese pterosaur with a preserved skull.1 2
仍有爭議: Scientists debate whether Haopterus was a specialized fish-eater or if it also ate other small animals, like its close relative Mimodactylus, which may have eaten crustaceans.1
