These are not the four-winged Microraptor. These are a Chinese pterosaur called Eosipterus.
— Allen, about Eosipterus

Eosipterus (name meaning "Yang's Dawn Wing") is a genus of pterosaurs that originated during the Early Cretaceous period in what is now China.


Era & DiscoveryEdit

Eosipterus lived in China during the Early Cretaceous period, over 125 million years ago. The genus was named in 1997 by Chinese paleontologists Ji Shu'an and Ji Qiang. 

Physical AttributesEdit

Eosipterus had a 7 foot (2.1 m) wingspan, making it rather small for a medium sized pterosaur. As a pterosaur, Eosipterus was from an exclusive group of backboned animals. Therefore, they were one of only three species that possessed the ability to preform powered flight.

They are described as the "birds and the bats" of the pterosaur world. Like all pterosaurs, Eosipterus possessed a membrane that was between their legs and the rest of their body. And it gave them the ability to do astonishing acrobatics in the air.

Behavior & TraitsEdit

Like many pterosaurs, Eospiterus lived in huge flocks and often ate fish, big and little animals, and dead animals. When looking for fish in rivers, ponds, lakes, or even in the ocean, they would fly directly down, skim the surface of the water and put their lower jaws in the water. When they felt something moving, their jaws snapped close akin to a snap trap.


  • The sound effects of Eosipterus are vulture, eagle, and pelican sound effects.
