名字的意思： “wing snout”1

吃：魚飛行爬蟲類侏羅紀中期嚴格來說不是恐龍

Pterorhynchus was a flying reptile that lived about 164 million years ago, during the Jurassic Period. It had a big crest on its head and a long tail, and it flew over ancient China.1 4

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

Pterorhynchus had a head crest made of both bone and soft tissue, which was unusual for long-tailed pterosaurs.1 2

Its body was covered in hair-like structures called pycnofibers, which may have helped keep it warm.1

The tail of Pterorhynchus was about as long as its wing, and it had a diamond-shaped flap at the end.1 2

The head crest was so large that scientists think it helped the animal steer while flying, like a rudder.2

The only known fossil is a nearly complete skeleton with preserved skin and other soft parts.1

The crest may have had a camouflage pattern, based on vertical stripes seen at its base.1

關於 Pterorhynchus 最常被問的問題

?How big was Pterorhynchus?

Pterorhynchus had a wingspan of about 85 centimetres (33 inches) and a skull about 11.8 centimetres (4.6 inches) long.1 3

?What did Pterorhynchus eat?

Its robust teeth suggest it ate small animals, possibly including fish and insects, though the exact diet is not known for sure.3

?Did Pterorhynchus have feathers?

Pterorhynchus had hair-like pycnofibers covering its body, not feathers. Some scientists think these might be related to dinosaur feathers, but this is debated.1

?Why did Pterorhynchus have a crest?

The crest likely helped with steering during flight, acting like a rudder, and may have had a camouflage pattern.1

迷思破解王

迷思： Pterorhynchus was a dinosaur.

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