Zhenyuanopterus

名字的意思： “Sun Zhenyuan's wing”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Zhenyuanopterus was a flying reptile that lived in ancient China. It had a long snout full of needle-like teeth and a wingspan as wide as a small car. It probably hunted fish by swooping down over lakes.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

Zhenyuanopterus had 86 teeth in its upper jaw and 86 in its lower jaw, all long and needle-like.1

Its longest front teeth were more than 10 times longer than its shortest teeth.1

The skull of the first fossil found measured 54.5 centimeters (21.5 inches) long.1

Zhenyuanopterus had a rectangular crest on top of its snout and a small crest at the back of its head.1

Some scientists think Zhenyuanopterus might actually be an adult of a smaller pterosaur called Boreopterus, because the differences could be due to age.1

It lived in a lakeside forest with volcanoes, alongside other pterosaurs like Boreopterus and Feilongus.1
