Samburupithecus
The one species in this genus, Samburupithecus kiptalami, is known only from a maxilla fragment dated to 9.5 million years ago discovered in 1982[1] and formally described by Ishida & Pickford 1997.[3] Samburupithecus lived during the so-called "African ape gap" 14 to 7 Ma, a period from which very few hominoid fossils have been found in Africa until relatively recently.[7] Defining cranial traits of this genus include low, broad zygomatics, straight alveolar process and large maxillary sinus.[9] These elongated teeth are unlike many other Miocene hominoids, linking Samburupithecus the taxon to gorillas, chimpanzees and hominins, but its relationships within this clade is at present unclear.[10] Because of this mixture of primitive and derived traits in the KNM-SH 8531 specimen, it has been proposed that Samburupithecus lived before the gorilla-chimpanzee-hominin split and, therefore, that it is a common ancestor to these primates alongside Ouranopithecus.
