The gelada, sometimes called the bleeding-heart monkey or the gelada baboon, is a species of Old World monkey found only in the Ethiopian Highlands, living at elevations of 1,800–4,400 m (5,900–14,400 ft) above sea level. It is the only living member of the genus Theropithecus, a name derived from the Greek root words for "beast-ape". Like its close relatives in genus Papio, the baboons, it is largely terrestrial, spending much of its time foraging in grasslands, with grasses comprising up to 90% of its diet.
Platybelodon is an extinct genus of large herbivorous proboscidean mammals related to modern-day elephants, placed in the "shovel tusker" family Amebelodontidae. Species lived during the middle Miocene Epoch in Africa, Asia and the Caucasus.
Elephas is one of two surviving genera in the family of elephants, Elephantidae, with one surviving species, the Asian elephant, Elephas maximus. Several extinct species have been identified as belonging to the genus, extending back to the Pliocene or possibly the late Miocene.
Theropithecus is a genus of primates in the family Cercopithecidae. It contains a single living species, the gelada, native to the Ethiopian Highlands.
Anancus is an extinct genus of "tetralophodont gomphothere" native to Afro-Eurasia, that lived from the Tortonian stage of the late Miocene until its extinction during the Early Pleistocene, roughly from 8.5–2 million years ago.
Gorgopithecus is an extinct genus of primate in the Old World monkey family Cercopithecidae, closely related to the baboons. There is only one known species, Gorgopithecus major. It has been found at sites from the Pliocene and Early Pleistocene Epoch in South Africa and Tanzania. It was first discovered at the Kromdraai A site in South Africa. It has since been found from Swartkrans, South Africa. Most recently, it has been recognized from the DKI site in Bed I of Olduvai Gorge, Tanzania, which has been dated to 1.8 million years old.
Dinopithecus is an extinct genus of very large primates closely related to baboons, that lived during the Pliocene and Pleistocene epochs in South Africa and Ethiopia. It was named by British paleontologist Robert Broom in 1937. The only species currently recognized is Dinopithecus ingens, as D. quadratirostris has been reassigned to the genus Soromandrillus. It is known from several infilled cave sites in South Africa, all of early Pleistocene age, including Skurweberg, Swartkrans, and Sterkfontein.
Protocyon is an extinct genus of large canid endemic to South and North America during the Late Pleistocene living from 781 to 12 thousand years ago.
Nina Grace Jablonski is an American anthropologist and palaeobiologist, known for her research into the evolution of skin color in humans. She is engaged in public education about human evolution, human diversity, and racism. In 2021, she was elected to the U.S. National Academy of Sciences and in 2009, she was elected to the American Philosophical Society. She is an Evan Pugh University Professor at The Pennsylvania State University, and the author of the books Skin: A Natural History, Living Color: The Biological and Social Meaning of Skin Color, and the co-author of Skin We Are In.
Ailuropoda baconi is an extinct panda known from cave deposits in South China, Laos, Vietnam, Myanmar, and Thailand from the Late Pleistocene, 750,000 years ago, and was preceded by A. wulingshanensis and A. microta as an ancestor of the giant panda. Very little is known about this animal; however, its latest fossils have been dated to the Late Pleistocene.
Morenelaphus is an extinct genus of capreoline deer that lived in South America during the Pleistocene, ranging from the Pampas to southern Bolivia and Northeast Brazil. There is only a single recognised species, Morenelaphus brachyceros. It was a large deer, with some specimens estimated to exceed 200 kilograms in body mass. The antlers were over 70 cm in length, and are superficially similar those of deer belonging to the subfamily Cervinae, like red deer. Fossils of the genus have been recovered from the Agua Blanca, Fortín Tres Pozos and Luján Formations of Argentina, the Ñuapua Formation of Bolivia, Santa Vitória do Palmar in southern Brazil, Paraguay and the Sopas Formation of Uruguay.
Cercopithecoides is an extinct genus of colobine monkey from Africa which lived during the latest Miocene to the Pleistocene period. There are several recognized species, with the smallest close in size to some of the larger extant colobines, and males of the largest species weighed over 50 kilograms (110 lb).
Mececyon trinilensis, the Trinil dog, is an extinct canid species that lived on the island of Java in Indonesia during the Pleistocene.
This paleomammalogy list records new fossil mammal taxa that were described during the year 2018, as well as notes other significant paleomammalogy discoveries and events which occurred during that year.
The Mid-Pleistocene Transition (MPT), also known as the Mid-Pleistocene Revolution (MPR), is a fundamental change in the behaviour of glacial cycles during the Quaternary glaciations. The transition lasted around 550,000 years, from 1.25 million years ago until 0.7 million years ago approximately, in the Pleistocene epoch. Before the MPT, the glacial cycles were dominated by a 41,000-year periodicity with low-amplitude, thin ice sheets, and a linear relationship to the Milankovitch forcing from axial tilt. Because of this, sheets were more dynamic during the Early Pleistocene. After the MPT there have been strongly asymmetric cycles with long-duration cooling of the climate and build-up of thick ice sheets, followed by a fast change from extreme glacial conditions to a warm interglacial. This led to less dynamic ice sheets. Interglacials before the MPT had lower levels of atmospheric carbon dioxide compared to interglacials after the MPT. One of the MPT's effects was causing ice sheets to become higher in altitude and less slippery compared to before. The MPT greatly increased the reservoirs of hydrocarbons locked up as permafrost methane or methane clathrate during glacial intervals. This led to larger methane releases during deglaciations. The cycle lengths have varied, with an average length of approximately 100,000 years.
Dental microwear analysis is a method to infer diet and behavior in extinct animals, especially in fossil specimens. Typically, the patterns of pits and scratches on the occlusal or buccal surface of the enamel are compared with patterns observed in extant species to infer ecological information. Hard foods in particular can lead to distinctive patterns. Microwear can also be used for inferring behavior, especially those related to the non-masticatory use of teeth as 'tools'. Other uses include investigating weaning in past populations. Methods used to collect data initially involved a microscope and manually collecting information on individual microwear features, but software to automatically collect data have improved markedly in recent years.
The Chinese orangutan is an extinct species of orangutan from the Pleistocene of South China. It is known from fossil teeth found in the Sanhe Cave, and Baikong, Juyuan and Queque Caves in Chongzuo, Guangxi. Its dental dimensions are 20% bigger than those of living orangutans. The youngest remains of the species date to between 57,000-66,000 years ago in Yincun Cave, Guangxi.
Tethytragus was a genus of caprine bovid that lived in the Middle and Late Miocene.
Palaeoreas was a genus of Miocene bovid from Europe.
