名字的意思： “hollow branch of the lower jaw”1

吃：魚飛行爬蟲類三疊紀晚期嚴格來說不是恐龍

Caviramus was a small flying reptile that lived about 205 million years ago, during the Late Triassic. It had a lightweight, hollow jaw and sharp teeth for catching fish. Caviramus is not a dinosaur, but a pterosaur, a close relative of dinosaurs.3 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

Caviramus had a jaw that was hollow and filled with air spaces, making it very light.1

Its teeth had multiple cusps, like little bumps, and were different in the front and back of the mouth.1

The only known fossil of Caviramus is a piece of the lower jaw, found in Switzerland.1

Caviramus lived in a shallow sea or lagoon, alongside sharks, fish, and other marine reptiles.1

Its wingspan was about 135 centimeters, which is a little over four feet.2

Some scientists think Caviramus might have searched for food on the ground, because its legs were long.2
