Liaoxipterus

名字的意思： “Liaoxi wing”1

吃：昆蟲飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Liaoxipterus was a flying reptile that lived about 120 million years ago. It had a short jaw with small, peg-like teeth, and it may have used its long tongue to catch insects, just like a chameleon!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。

趣味知識

Liaoxipterus was the first istiodactylid pterosaur found in China, but scientists first thought it was a different kind of pterosaur called a ctenochasmatid.2

Its lower jaw was about 161 millimetres long, which is shorter than a ruler, and it had about 26 teeth in total.1 2

The hyoid bone in its throat was Y-shaped and very long, similar to a chameleon's, which helps the tongue shoot out to catch prey.2

Liaoxipterus lived alongside other pterosaurs like Nurhachius and Istiodactylus sinensis in the same ancient environment.2

Its teeth were all the same shape, with roots longer than the crowns, and they were flattened from side to side.2

Scientists think the wide tip of its lower jaw might have been different from other pterosaurs because of sexual differences, like males and females looking different.2

迷思： Liaoxipterus was a dinosaur.

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

類群: 飛行爬蟲類
科 / 演化支: Istiodactylidae3
分類: Pterosauria > Pterodactyloidea3
岩石的年代: 121 到 113 百萬年 (Aptian)3
岩層: Jiufotang3
國家: 中國3
化石紀錄: The Paleobiology Database 收錄 1 筆3
發現: Liaoxipterus was named by Dong Zhiming and Lü Junchang in 2005, based on a nearly complete lower jaw found in the Jiufotang Formation in China.1 3
仍有爭議: Scientists still debate whether Liaoxipterus is the same as another pterosaur called Nurhachius, because some studies say they are different, while others suggest they might be the same.1 2
