Martinavis is a genus of enantiornithine birds which existed in what is now southern France, North America and Salta Province, Argentina during the late Cretaceous period. It was named by Cyril A. Walker, Eric Buffetaut and Gareth J. Dyke in 2007, and the type species is Martinavis cruzyensis. M. cruzyensis is known from the holotype ACAP-M 1957, a complete uncrushed right humerus, recovered from the Massecaps locality, Cruzy, which is in a Campanian/Maastrichtian-stage deposits in the Grès à Reptiles Formation of France. A second species, M. vincei is known from the holotype PVL 4054, a complete left humerus and from the associated paratype PVL 4059, a distal end of left humerus, recovered from the El Brete locality (Maastrichtian age), Lecho Formation of Argentina. A possible third species is represented by the unnamed specimen KU-NM-37 from USA.[1] In 2009, three additional species were named from the same location as M. vincei. M. minor is known from the holotype PVL 4046, a distally imperfect right humerus, M. saltariensis is known from the holotype PVL 4025, an incomplete left humerus, lacking the median ridge and M. whetstonei is known from the holotype PVL 4028, a distally imperfect left humerus.[2]
