A new species of Lovebird (Aves, Psittaculidae, Agapornis) from the Plio-Pleistocene of the Cradle of Humankind (Gauteng, South Africa)

International audience ; A new parrot species of the genus Agapornis (Aves, Psittaculidae), namely Agapornis longipes nov. sp., is described from the Plio-Pleistocene of Kromdraai, Cooper's Cave, and Swartkrans in the Cradle of Humankind, South Africa. The new species is represented by all major wing bones (humerus, ulna, and carpometacarpus) and by the tarsometatarsus, together with a fragmentary mandible and coracoid. The size of the bones indicates a small species of Agapornis with an elongated tarsometatarsus, proportionately the longest of all known species of Agapornis. This lengthening of the legs might be related to feeding adaptation of the extinct species, as the longer legs may have favored this ground feeder in the high and dense grassland characteristic of the Cradle of Humankind during the Plio-Pleistocene transition and the Early Pleistocene.
