Sinopterus

名字的意思： “Chinese wing”1

吃：植物飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Sinopterus was a flying reptile with a big, toothless beak like a parrot. It lived in China during the Early Cretaceous, about 120 million years ago, and probably ate plants and seeds.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

Sinopterus had a long, bony crest on top of its skull that pointed backward like a spike.1

Its beak had no teeth, similar to modern birds and some other pterosaurs.1

Scientists found tiny plant fossils (phytoliths) in the stomach of a Sinopterus, proving it ate plants.1

Sinopterus also swallowed small stones (gastroliths) to help grind up tough plant food in its gizzard.1

It was one of the first tapejarid pterosaurs found outside Brazil, showing these flying reptiles lived in many places.1

The largest Sinopterus had a wingspan of about 1.9 metres (6.2 feet) and weighed around 2.9 kilograms (6.3 pounds).1

Many scientists now think that only one species of Sinopterus is valid: Sinopterus dongi.2
