Yatenavis (meaning "stone bird") is an extinct genus of enantiornithine bird from the Late Cretaceous Chorrillo Formation of Santa Cruz Province, Argentina. The genus contains a single species, Y. ieujensis, known from a partial humerus.[1]
The Yatenavis holotype specimen, MPM-PV-23086, was discovered in sediments of the Chorrillo Formation near Estancia La Anita, Calafate, Santa Cruz Province, Argentina. This specimen consists of the distal right humerus.[1]
In 2022, Herrera et al. described Yatenavis ieujensis, a new genus and species of enantiornithine, based on these fossil remains. The generic name, "Yatenavis", combines the Aonikenk word for "stone" with the Latin word "avis", meaning "bird". The specific name, "ieujensis", is derived from "ieuj", the Aonikenk word for "snow". Yatenavis represents the eighth enantiornithine named from South America.[1]
