Gansus is an advanced short-tailed Avialian bird from early Cretaceous China. The type species is G. yumenensis.


The holotype of Gansus was a piece of an isolated left leg bone. Gansus is closely related to the ancestor of all modern birds. It had a wingspan of 40 centimeters and a length of 24 centimeters. The wings of Gansus were large and powerful, and it had a strongly keeled breastbone. Gansus was likely able to fly, as well as swim using its wings and feet.


Webbed feet and heavier wings suggest it was a foot-propelled diver, similar to extant loons and grebes. It likely had a similar niche to said birds, catching small fish.
