African wild ass descendant. Thus, if one species is recognized, the correct scientific name of the donkey is "E. africanus asinus". The first published name for the African wild ass, "Asinus africanus", Fitzinger, 1858, is a nomen nudum. The name "Equus taeniopus" von Heuglin, 1861 is rejected as indeterminable, as it is based on an animal that cannot be identified and may have been a hybrid between a domestic donkey and a Somali wild ass; the type has not been preserved. The first available name thus becomes "Asinus africanus" von Heuglin & Fitzinger, 1866. A lectotype is designated: a skull of an adult
Australopithecus africanus of the Witwatersrand in Johannesburg, South Africa, became interested in fossils found at a limestone quarry at Taung near Kimberley, South Africa in 1924. The most promising of these was a skull of an odd ape-like creature presenting human traits at the eye orbits, teeth, and, most importantly, the hole at the base of the skull over the spinal column (the foramen magnum); its placement indicated a human-like upright posture and implied a high probability that this hominid-to-hominin primate had achieved bipedal, as opposed to quadrupedal locomotion. Dart assigned the specimen the name "Australopithecus africanus" ("southern ape of Africa"); it
