       Martinavis is a genus of enantiornithine bird which lived during the late Cretaceous.‭ ‬So far Martinavis is known from several species,‭ ‬and fossils discovered in France,‭ ‬Argentina as well potential remains in the USA.‭ ‬If all these fossils are valid,‭ ‬then at a genus level,‭ ‬Martinavis would have been one of the most widespread enantiornithine birds.
