名字的意思： “Great Wall wing”1

吃：魚飛行爬蟲類侏羅紀中期到侏羅紀晚期嚴格來說不是恐龍

Changchengopterus was a small flying reptile that lived in China during the Jurassic Period. It had long, thin wings and probably ate fish by snapping them up from the water.3 1

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

Changchengopterus is known from two fossils: a young juvenile and an adult. The juvenile's wing bones measured only 17 centimetres (about 6.7 inches) in total.1

Its name comes from the Great Wall of China (Changcheng) and the Greek word for wing (pteron).1

Scientists are not sure exactly where Changchengopterus sits on the pterosaur family tree. Some studies place it close to Dorygnathus, others with the wukongopterids, and some even outside the group Monofenestrata.1

The first fossil was collected by Pan Lijun, who donated it to science. The species name pani honors him.1

Changchengopterus lived about 163 million years ago, during the Middle Jurassic.1
