Fun facts
Zhenyuanopterus had 86 teeth in its upper jaw and 86 in its lower jaw, all long and needle-like.1
Its longest front teeth were more than 10 times longer than its shortest teeth.1
The skull of the first fossil found measured 54.5 centimeters (21.5 inches) long.1
Zhenyuanopterus had a rectangular crest on top of its snout and a small crest at the back of its head.1
Some scientists think Zhenyuanopterus might actually be an adult of a smaller pterosaur called Boreopterus, because the differences could be due to age.1
It lived in a lakeside forest with volcanoes, alongside other pterosaurs like Boreopterus and Feilongus.1
