吃：魚飛行爬蟲類侏羅紀晚期嚴格來說不是恐龍

Kryptodrakon was an early flying reptile that lived about 162 million years ago. It was one of the first pterosaurs with a long wing finger, which helped it fly better. This small dragon-like creature had a wingspan of about 1.4 metres (4.6 feet).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

Kryptodrakon is the oldest known pterodactyloid pterosaur, meaning it had a long wing finger that made it a better flyer than earlier pterosaurs.2

Its name means 'hidden dragon' because it was discovered in a remote part of China and its fossils were hidden in rocks.1

Kryptodrakon lived in a river environment, which is unusual because many pterosaurs lived near the sea. This suggests it was adapted to life on land.2

The wing metacarpal bone of Kryptodrakon shows a mix of old and new features, with a primitive top part and a more advanced bottom part.2

Scientists think Kryptodrakon was an adult when it died because its shoulder and wrist bones were fused together.2
