吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Pterofiltrus was a flying reptile that lived about 125 million years ago. It had a very long, narrow skull and lots of thin, pointy teeth that it used like a strainer to catch tiny animals in the water.1 2

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

Pterofiltrus had about 112 teeth in its head, which is a lot for a pterosaur.1 2

Its teeth covered more than half of the skull length, about 55.8%.1

The skull of Pterofiltrus was very long, about 208 millimetres (8.2 inches).1 2

Pterofiltrus had no bony crest on its head, unlike some other pterosaurs.1

Its lower jaw was also long, about 174 millimetres (6.9 inches), and had about 27 teeth.1

The front teeth of Pterofiltrus were longer than the back ones and pointed partly sideways.1

發現: Pterofiltrus was named by scientists Jiang Shunxing and Wang Xiaolin in 2011. The only known fossil, a skull and some neck bones, was found at Zhangjiagou in Liaoning, China.1 2
仍有爭議: Scientists are not sure exactly how Pterofiltrus used its many teeth to catch food, but they think it may have strained small animals from the water.1
