Harrisonavis

Harrisonavis is an extinct genus of flamingo that lived during the Late Oligocene and Early Miocene periods in what is now France. Despite being one of the oldest known members of the flamingo family, it already shows a skull remarkably similar to that of the modern greater flamingo. Although generally similar, it subtly differs in the curvature of the bill and the size of the ventral keel of the maxilla, both signs that Harrisonavis was not yet as adapted towards filter feeding as modern species are. Harrisonavis inhabited brackish lakes alongside the more basal Palaelodidae. It contains the single species Harrisonavis croizeti, first described in 1852.
