Neuquenornis ("Bird from Neuquén Province")is an extinct Enantiornithine bird from late Cretaceous Argentina. The type species is N. volans


The holotype of Neuquenornis is a partial skeleton that contains a skull and postcranial remains. Neuquenornis had a wingspan of more than 30 centimeters, a body length of 15 to 23.5 centimeters, a hip height of 17 cm, and a weight of 205 grams. Other known specimens are eggs with embryos. Neuquenornis had long, slender legs, with hooked claws.


The legs and claws of Neuquenornis show that it was adept at perching as well as gathering food from the ground or shallow water, which would be useful due to its habitat of open plains near dense forests. Neuquenornis likely shared behavior with megapode birds when it comes to protecting eggs. Neuquenornis may have also been social birds due to large colonies of their eggs having been discovered.
