ເລື່ອງໜ້າຮູ້ມ່ວນໆ
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
