Résumé :	The Middle Eocene locality of Eocliff, Namibia, has yielded a rich vertebrate fauna, including mainly mammals, but also a few bird remains. A coracoid and a scapula are ascribed to a new genus and a new species of galliform in the extinct family Paraortygidae. This family was so far known only from the Late Eocene and Early Oligocene of the northern hemisphere. A distal part of tarsometatarsus is ascribed to a new genus and a new species of psittaciform. This tarsometatarsus shows a trochlea metatarsi IV which is characteristic of the crown group Psittaciformes, but, in other features, it is different from extant parrots and corresponds to a stem group Psittaciformes.
