O. rothii Contents |
Oioceros is an extinct genus of spiral-horned antelope from the late Miocene. Its fossils have been found in Greece, [1] China, [2] Iran, and Africa. It was first discovered by Wagner in 1857, and contains nine species, O. rothii, O. atropatenes, O. jiulongkouensis, O. noverca, O. robustus, O. stenocephalus, O. lishanensis, O. wegneri, and O. tanyceras. Former species include O. grangeri (Pilgrim, 1934), now recognized as the genus Sinomegoceros , and O. xiejiaensis (Li and Qui; 1980), now recognized as the genus Sinopalaeoceros . [2]
In 1997, an almost complete skull of O. rothii proved that it was similar to Samotragus praecursor, with a short face, compared to its relatively long braincase, and isolated horn cores. [1] However, unlike S. praecursor, O. rothii had a jaw of primarily premolar teeth, which were longer than the molars found in the latter. [1] Pilgrim and Hopwood described the genus as being "small size with long slender muzzle; face bent down on basicranial axis either slightly or to a moderate extent; orbits with expanded orbital roof; horn-cores twisted counter-clockwise in a fairly close spiral of one or two revolutions, widely separate, tilted backward or fairly upright, divergent, with a cross-section almost circular or elliptical, keeled either anteriorly or posteriorly or both; dentition moderately hypsodont, premolar series rather long and slender, molars broad with ribs of medium strength" (Pilgrim and Hopwood, 1928, p. 24). The horn cores of Oioceros have a torsion. [4]
Metailurus is a genus of saber-toothed cat in the family Felidae, and belonging to the tribe Metailurini, which occurred in North America, Eurasia and Africa from the Miocene to the Middle Pleistocene.
Amphicyon is an extinct genus of large carnivorans belonging to the family Amphicyonidae, subfamily Amphicyoninae, from the Miocene epoch. Members of this family received their vernacular name for possessing bear-like and dog-like features. They ranged over North America, Europe, Asia, and Africa.
Herpestes is a genus within the mongoose family Herpestidae. Several species in the family are known as slender mongooses. It is the type genus of the family, and comprises 5-6 living species, each with several subspecies. Fossil remains of three prehistoric species were excavated in France, and described in 1853.
Gazella praegaudryi was a small species of prehistoric gazelle described from late Miocene sediments near Bou Hanifia, Algeria. It had lightly compressed horn cores and no forward turning metaconid of its P4 premolars, differentiating it from the earlier Miocene Gazella dentition recovered at Fort Ternan.
Aphelops is an extinct genus of hornless rhinocerotids endemic to North America. It lived from the Middle Miocene to the early Pliocene, during which it was a common component of North American mammalian faunas along with Teleoceras.
Wabulacinus ridei lived during the early Miocene in Riversleigh. It is named after David Ride, who made the first revision of thylacinid fossils. The material was found in system C of the Camel Spurtum assembledge.
The Macropodidae are an extant family of marsupial with the distinction of the ability to move bipedally on the hind legs, sometimes by jumping, as well as quadrupedally. They are herbivores, but some fossil genera like Ekaltadeta are hypothesised to have been carnivores. The taxonomic affiliations within the family and with other groups of marsupials is still in flux.
Galerix kostakii is a fossil erinaceid mammal from the early Miocene of Greece. It is known from the site of Karydia, assigned to the biostratigraphical zone MN 4; similar fossils have been found at an approximately contemporary Czech site and a slightly younger Greek site. With characters like the presence of a hypocone on the upper third premolar, the presence of a connection between the protocone and metaconule cusps on the second upper molar in only a few specimens, this species is intermediate between the slightly older Galerix symeonidisi and the slightly younger Parasorex pristinus. It may form part of the lineage leading from the genus Galerix to the younger genus Parasorex.
Deccanolestes is a scansorial, basal Euarchontan from the Late Cretaceous (Maastrichtian) and Paleocene Intertrappean Beds of Andhra Pradesh, India. It may be closely related to Sahnitherium. Deccanolestes has been referred to Palaeoryctidae in the past, but recent evidence has shown that it is either the most basal Euarchontan, as the earliest known Adapisoriculid, or as a stem-afrotherian.
Pristifelis is an extinct genus of feline from the late Miocene. It contains a single species, Pristifelis attica. The first fossil skull of P. attica was excavated near Pikermi in Attica, Greece. Fossils were also excavated near the Moldovan city of Taraclia. It was also discovered in Maragheh, northwestern Iran. P. attica was bigger in body size than a European wildcat but probably smaller than a serval. The species was first described as Felis attica by Johann Andreas Wagner in 1857. Due to size differences, it was proposed as type species for the genus Pristifelis proposed in 2012.
Sivaladapis is a genus of adapiform primate that lived in Asia during the middle Miocene.
Promephitis is an extinct genus of mephitid, of which several species have been described from the Miocene and early Pliocene of Europe and Asia.
Tragoportax is an extinct genus of bovid ungulate. It lived during the upper Miocene, and its fossil remains have been found in Europe, Asia and Africa.
Megadolodus is an extinct genus of proterotheriid litopterns.
Tetragonostylops is an extinct genus of mammal, related to Astrapotheria. It lived during the Late Paleocene, and its fossils were discovered in South America.
Astrapothericulus is an extinct genus of mammals, belonging to the order Astrapotheria. It lived during the Lower Miocene in what is now South America.
Altitypotherium is an extinct genus of Notoungulate, belonging to the suborder Typotheria. It lived during the Early Miocene, and its fossilized remains were discovered in South America.
Villarroelia is an extinct genus of proterotheriid from the Middle Miocene of Colombia.
Boleatherium is an extinct genus of interatheriid notoungulate that lived from the Early to Middle Miocene of what is now Argentina. Fossils of this genus have been found in the Cerro Boleadoras Formation, the formation which this genus was named after.
Vishnufelis is an early fossil genus of feline containing only a single species, Vishnufelis laticeps. It was described by Guy Ellcock Pilgrim in 1932, based on the first felid cranial material found in Asia: a fragmented skull found in the Chinji Formation, which dates back to the middle Miocene.
