Mfundo zosangalatsa

1

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

2

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

3

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

4

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

5

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

6

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

7

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

?Why did Sinopterus have a crest?

The long bony crest on its skull may have been used for display, such as attracting mates or recognizing other members of its species. Scientists are not completely sure.1

Wothetsa nthano zabodza

Sinopterus was named in 2002 by Chinese paleontologists Wang Xiaolin and Zhou Zhonghe, based on a nearly complete skeleton found in Liaoning, China.13

Scientists still debate how many different species of Sinopterus existed, because the crests and sizes vary a lot among fossils.2
