Avolatavis

Avolatavis is an extinct genus of stem-parrot or a member of the stem group of Psittacopasseres, known from the early Eocene Fossil Butte Member of the Green River Formation of Wyoming, United States, and from the London Clay of Walton-on-the-Naze. It was first named by Daniel T. Ksepka and Julia A. Clarke in 2012 and the type species is Avolatavis tenens. Gerald Mayr and Andrew C. Kitchener described the second species, A. europaeus, in 2023. Mayr and Kitchener assigned Avolatavis to the family Vastanavidae, which might be early diverging stem group presentatives of Pan-Psittaciformes or stem group representatives of Psittacopasseres.
