名字的意思： “dawn wing”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Eosipterus was a flying reptile that soared over ancient lakes in China about 125 million years ago. It had long, slender wings and a short tail, and it probably scooped up fish with its beak.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

Eosipterus was the first pterosaur ever found in western Liaoning Province, China.1 2

Its wingspan was about 1.2 meters (3.9 feet), making it a medium-sized pterosaur.1 2

The fossil of Eosipterus is missing its skull and neck, so scientists are not sure what its head looked like.1

Eosipterus had a short tail and strong forelimbs, which are features of advanced pterosaurs called pterodactyloids.1 2

Its fifth toe was reduced to a single claw, a sign that it was evolving away from walking on the ground.1

Eosipterus lived alongside the early bird Confuciusornis in the same ancient ecosystem.2
