Alexornis antecedens is an enantiornithine bird from the Late Cretaceous (~80 Ma) of Baja California, Mexico. A small arboreal bird, it was one of the first Mesozoic birds described from Mexico. Named by Brodkorb in 1976, it inhabited subtropical forest environments along the western coast of ancient North America. It contributes to understanding enantiornithine distribution across Cretaceous Laurasia.
