Jeholopterus ninchengensis was a small Anurognathid pterosaur from middle to late Jurassic China. It had a wingspan of 20 centimeters long. It currently includes one species; J. ninchengensis. Jeholpterus was an insectivore but may have also eaten fish. Despite its small size, it is one of the largest anurognathids.



The name Jeholopterus means Jehol (the area of China where it was discovered) wing. The pterosaur was named in 2002 by Wang Xiaolin, Zhou Zhonghe and Xu Xing.


Jeholopterus was a very small pterosaur with a wingspan of 80 centimeters. It had a roundish head and large eyes. In its mouth were pointed teeth that resembled pegs. The holotype has traces of Pycnofeathers on it along with wing tissue.[1] In 2009, scientists discovered layers of Pycnofeathers on the animals wings.[2]


Jeholopterus was part of the family Anurognathidae and part of the Anurognathinae subfamily.


Anurognathids were most likely nocturnal due to their large eyes. Jehlopterus's diet was likely composed of insects although it also may have included fish [3]

In Popular Culture[]

  • Jeholopterus makes its first video game appearance in Jurassic World Evolution 2 via the Feathered Species Pack released on March 30th, 2023. It is depicted with small tufts of feathers above its eyes, and very colorful wings. The overall anatomy is pretty accurate.
