Cratoavis is a genus of enantiornithines. The type and only currently described species is C. cearensis, from the Early Cretaceous of Araripe Basin, Ceará, Brazil . The fossil, an articulated skeleton with feathers attached to the wings and surrounding the body, extends considerably the temporal record of the group at South America.[1]

The genus was named after the Crato Formation, in which the specimen was found.[1]
