Eoazhdarcho

名字的意思： “dawn Azhdarcho”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Eoazhdarcho was a small flying reptile that lived in the Early Cretaceous period, about 120 million years ago. It had a wingspan of about 1.6 metres (5.2 feet) and probably ate fish. Its fossils were found in Liaoning, China.1 3

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

Eoazhdarcho is known from a partial skeleton and lower jaw, found in the Jiufotang Formation of China.1

Its name means 'dawn Azhdarcho' because it was an early relative of the larger pterosaur Azhdarcho.1

Scientists think Eoazhdarcho belonged to a group called Chaoyangopteridae, which are close cousins of the giant azhdarchids.1

The ratio of its humerus (upper arm bone) to femur (thigh bone) is about 0.96, meaning its arms and legs were almost the same length.2

Eoazhdarcho lived around 120 million years ago, during the Aptian age of the Early Cretaceous.1 3
