Mioeuoticus is an extinct genus of lorisid primates from the Miocene of East Africa. It is the only genus in the subfamily Mioeuoticinae. [1] Mioeuoticus was a relatively small, potto-sized animal with an omnivorous diet consisting of fruit and insects. [2]
Apes are a clade of Old World simians native to sub-Saharan Africa and Southeast Asia, which together with its sister group Cercopithecidae form the catarrhine clade, cladistically making them monkeys. Apes do not have tails due to a mutation of the TBXT gene. In traditional and non-scientific use, the term "ape" can include tailless primates taxonomically considered Cercopithecidae, and is thus not equivalent to the scientific taxon Hominoidea. There are two extant branches of the superfamily Hominoidea: the gibbons, or lesser apes; and the hominids, or great apes.
Lemuriformes is an infraorder of primate that falls under the suborder Strepsirrhini. It includes the lemurs of Madagascar, as well as the galagos and lorisids of Africa and Asia, although a popular alternative taxonomy places the lorisoids in their own infraorder, Lorisiformes.
Merycopotamus is an extinct genus of Asian anthracothere that appeared during the Middle Miocene, and died out in the Late Pliocene. At the height of the genus' influence, species ranged throughout southern Asia. With the extinction of the last species, M. dissimilis, the lineage of anthracotheres came to an end. Merycopotamus was closely related to the anthracothere genus Libycosaurus, which, unlike the former, never left Africa. In fact, some African fossils originally placed in Merycopotamus, but are now referred to Libycosaurus.
Nakalipithecus nakayamai is an extinct species of great ape from Nakali, Kenya, from about 9.9–9.8 million years ago during the Late Miocene. It is known from a right jawbone with 3 molars and from 11 isolated teeth, and the specimen is presumed female as the teeth are similar in size to those of female gorillas and orangutans. Compared to other great apes, the canines are short, the enamel is thin, and the molars are flatter. Nakalipithecus seems to have inhabited a sclerophyllous woodland environment.
Martin Pickford was lecturer in the Chair of Paleoanthropology and Prehistory at the Collège de France and honorary affiliate at the Département Histoire de la Terre in the Muséum national d'Histoire. In 2001, Martin Pickford together with Brigitte Senut and their team discovered Orrorin tugenensis, a hominid primate species dated between 5.8 and 6.2 million years ago and a potential ancestor of the genus Australopithecus.
Samburupithecus is an extinct primate that lived in Kenya during the middle to late Miocene. 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 and formally described by Ishida & Pickford 1997. The type specimen KNM-SH 8531 was discovered by the Joint Japan-Kenya Expedition at the SH22 fossil site in the Samburu District, a locality where several other researchers found no ape fossils.
Dendropithecus is an extinct genus of apes native to East Africa between 20 and 15 million years ago. Dendropithecus was originally suggested to be related to modern gibbons, based primarily on similarities in size, dentition, and skeletal adaptations. However, further studies have shown that Dendropithecus lacks derived hominoid traits. Instead, the traits shared between this taxon and modern primates are primitive for all catarrhines. Dendropithecus is now considered to be a stem catarrhine, too primitive to be closely related to any modern primates.
Kamoyapithecus was a primate that lived in Africa during the late Oligocene period, about 24.2-27.5 million years ago. First found in 1948 as part of a University of California, Berkeley expedition, it was at first thought to be under a form of Proconsul by C.T. Madden in 1980, but after a re-examination by Meave Leakey and associates later, the fossils were moved under a new genus Kamoyapithecus, named after the renowned fossil finder Kamoya Kimeu. The genus is represented by only one species, K. hamiltoni.
? Nycticebus linglom is a fossil strepsirrhine primate from the Miocene of Thailand. Known only from a single tooth, an upper third molar, it is thought to be related to the living slow lorises, but the material is not sufficient to assign the species to Nycticebus with certainty, and the species name therefore uses open nomenclature. With a width of 1.82 mm, this tooth is very small for a primate. It is triangular in shape, supported by a single root, and shows three main cusps, in addition to various crests. The absence of a fourth cusp, the hypocone, distinguishes it from various other prosimian primates.
Khoratpithecus is an extinct genus of pongin primates that lived during the late Miocene in Myanmar and Thailand.
Nacholapithecus kerioi was an ape that lived 14-15 million years ago during the Middle Miocene. Fossils have been found in the Nachola formation in northern Kenya. The only member of the genus Nacholapithecus, it is thought to be a key genus in early hominid evolution. Similar in body plan to Proconsul, it had a long vertebral column with six lumbar vertebrae, no tail, a narrow torso, large upper limbs with mobile shoulder joints, and long feet.
Komba is an extinct genus of galagos, containing species known from the early to middle Miocene of Kenya and Uganda. A new species, K. walkeri, was described from the early Miocene of Kenya by Terry Harrison in 2010.
Simiolus is an extinct genus of dendropithecid primates. It was described by Mary Leakey and Richard Leakey in 1987, and the type species is S. enjiessi, which existed during the Miocene of Kenya. The species epithet is a phonetic pun on the acronym NGS. A new species, S. andrewsi, also from the middle Miocene of Kenya, was described by Terry Harrison in 2010. In November 2018, scientists reported the discovery of the smallest known ape, Simiolus minutus, which weighed approximately eight pounds, and lived about 12.5 million years ago in Kenya in East Africa.

The phylogenetic split of Hominidae into the subfamilies Homininae and Ponginae is dated to the middle Miocene, roughly 18 to 14 million years ago. This split is also referenced as the "orangutan–human last common ancestor" by Jeffrey H. Schwartz, professor of anthropology at the University of Pittsburgh School of Arts and Sciences, and John Grehan, director of science at the Buffalo Museum.
Pliopithecoidea is an extinct superfamily of catarrhine primates that inhabited Asia and Europe during the Miocene. Although they were once a widespread and diverse group of primates, the pliopithecoids have no living descendants.
The family Dendropithecidae is an extinct family of catarrhine monkeys. They date from the Early Miocene, around 20 - 12 million years ago.
Nyanzapithecus pickfordi is an extinct species of primate from the Middle Miocene of Maboko Island, Nyanza Province, Kenya. It had an average body mass of around 10 kg (22 lb).
The Hiwegi Formation is a geological formation on Rusinga Island in Kenya preserving fossils dating to the Early Miocene period. The Hiwegi Formation is known for the well preserved plant fossils it preserves, which indicate a tropical forest environment that underwent wet and dry periods. The middle members of the formation in particular indicate a brief period in which conditions were notably dryer with a more open environment compared to older and younger units. Some of the formation's fauna, such as an early ancestor of the modern aye-aye and a chameleon of the genus Calumma, link Miocene East Africa to modern day Madagascar.
