Chaoyangopterus

名字的意思： “Chaoyang wing”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Chaoyangopterus was a flying reptile that lived in China during the Early Cretaceous. It had a long, toothless beak and a wingspan about as wide as a small car. It probably swooped down to catch fish from lakes.1 5

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

Chaoyangopterus had no teeth, just a sharp beak like a bird.1

Its skull was about 27 centimeters (11 inches) long, about the size of a ruler.1

It still had four fingers on each hand, unlike some other pterosaurs that lost fingers.1

Its legs were longer and its wings shorter compared to its relative Nyctosaurus.1

Scientists first thought Chaoyangopterus was a nyctosaurid, but later placed it in its own family, Chaoyangopteridae.1

Some researchers now think Chaoyangopterus might have been an omnivore that walked on the ground like a crane, instead of just eating fish.1 5
