Katifelis
''Katifelis'' is an extinct genus of felids that lived in what is now Kenya during the Early Miocene and is notable for its dental features, which are intermediate between basal and modern cats. It contains a single species, ''Katifelis nightingalei''. Discovery and naming The holotype; and so far only fossil, of ''Katifelis'' was discovered at the locality Kalodirr, which is part of the Lothidok Formation. The site is dated to 17.5 ± 0.2 Ma – 16.8 ± 0.2 Ma and located in West Turkana, Kenya. The type specimen KNM-WK17133 is a left mandibular fragment, containing the teeth p1-m1. Described in 2018, it is the second felid with transitional traits known from Early Miocene Africa, alongside the slightly older '' Asilifelis''. After the appearance of ''Katifelis'' during the late Burdigalian there are no fossil records of any African felids until the appearance of '' Machairodus'' around 12.5 Ma. The generic name is a combination of Swahili ''Kati'' (“intermediate”), ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asilifelis
''Asilifelis'' is an extinct genus of small felid that lived in what is now Kenya during the Early Miocene. Despite its fragmentary remains, it is remarkable because of its small size and advanced dentition. It contains a single species, ''Asilifelis cotae''. Discovery and naming ''Asilifelis'' is only known from a single specimen: KNM RU 18349, a mandibular ramus, including the well-preserved teeth p4-m1, which is stored in the National Museums of Kenya. The fossil was discovered in rocks of the Hiwegi Formation on Rusinga Island in 1949, but was subsequently only mentioned once in scientific literature until its description by Lars Werdelin in 2012. The generic name is a combination of Swahili asili ("origin") and Latin felis ("cat"). The species name "cotae" honors Susanne Cote, who inspired Werdelin's interest in Miocene Africa. Description ''Asilifelis'' is much smaller than other Early Miocene felids, comparable in size to the smallest extant species, such as the ...

Diamantofelis
''Diamantofelis'' is an extinct genus of Felidae, felids that lived in what is now Namibia during the Early Miocene. It contains a single species, ''Diamantofelis ferox.'' Discovery and naming This genus was described in 1998 on the basis of remains discovered at the locality of Arrisdrift in Namibia, which has been dated to 17.5 – 17 Ma. The holotype (AD 98'95), is a left mandible which includes the canine and cheek teeth. In 2003 various postcranial remains belonging to this genus were described. These include the first Phalanx bone, phalanx (AD 601'99) as well as, the proximal end of a left ulna (AD 112'94) Furthermore, the fragments of another ulna (AM 2'99), found at the slightly older locality Auchas, which dates to ca. 19 Ma, were referred to ''Diamantofelis''. A second species named ''Diamantofelis minor'' was originally described from the same locality, but has since been moved to the genus ''Namafelis''. These two genera are notable for being the first, and until the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burdigalian
The Burdigalian is, in the geologic timescale, an age (geology), age or stage (stratigraphy), stage in the early Miocene. It spans the time between 20.43 ± 0.05 annum, Ma and 15.97 ± 0.05 Ma (million years ago). Preceded by the Aquitanian (stage), Aquitanian, the Burdigalian was the first and longest warming period of the MioceneEdward Petuch, Ph.D. Florida Atlantic University, Department of Geosciences. and is succeeded by the Langhian. Stratigraphic definition The name Burdigalian comes from ''Burdigala'', the Latin name for the city of Bordeaux, France. The Burdigalian Stage was introduced in scientific literature by Charles Depéret in 1892. The base of the Burdigalian is at the first appearance of foram species ''Globigerinoides altiaperturus'' and the top of magnetic chronozone C6An. , an official GSSP for the Burdigalian had not yet been assigned. The top of the Burdigalian (the base of the Langhian) is defined by the first appearance of foram species ''Praeorbulina gl ...

Thryonomyidae
Thryonomyidae is a family of hystricognath rodents that contains the cane rats ''(Thryomys)'' found throughout sub-Saharan Africa, and a number of fossil genera. Taxonomy Thryonomyidae was formerly more diverse and widespread, with fossil relatives found in India and Arabia as well. The extinct genus '' Sacaresia'' from the island of Mallorca off Spain may also be a member of this family, though its position remains uncertain. *Genus †'' Epiphiomys'' **†''Epiphiomys coryndoni'' *Genus †'' Gaudeamus'' **†''Gaudeamus aegyptius'' *Genus †'' Kochalia'' **†''Kochalia geespei'' *Genus †'' Monamys'' **†''Monamys simonsi'' *Genus †'' Neosciuromys'' **†''Neosciuromys africanus'' *Genus †'' Paraphiomys'' **†''Paraphiomys afarensis'' **†''Paraphiomys hopwoodi'' **†''Paraphiomys knolli'' **†''Paraphiomys occidentalis'' **†''Paraphiomys orangeus'' **†''Paraphiomys pigotti'' **†''Paraphiomys renelavocati'' **†''Paraphiomys shipmani'' *Genus †'' Paraul ...

Isohyaenodon
''Isohyaenodon'' ("equal to Hyaenodon") is an extinct polyphyletic genus of hyainailourid hyaenodont mammal from polyphyletic subtribe Isohyaenodontina (of the polyphyletic tribe Hyainailourini within paraphyletic subfamily Hyainailourinae). Remains are known from early to middle Miocene deposits in Kenya, East Africa. Description ''Isohyaenodon'' is distinguished from ''Hyaenodon'' in having more robust molars, lower molars with a subequal paraconid and protoconid, and upper molars with a more well-developed protocone. Classification and phylogeny Taxonomy ''Isohyaenodon'' was considered possibly the same genus as '' Leakitherium'' from the same region by Van Valen (1967), but subsequent studies have rejected this assumption. ''Isohyaenodon pilgrimi'' Savage, 1965 was formerly assigned to this genus, but has been renamed '' Exiguodon pilgrimi''. Phylogeny The phylogenetic relationships of genus ''Isohyaenodon'' are shown in the following cladogram: See also * Mammal classi ...

Giraffoidea
Giraffoidea is a superfamily that includes the families Climacoceratidae, Antilocapridae, and Giraffidae. The only extant members in the superfamily are the pronghorn, giraffe, and okapi. The Climacoceratidae are also placed in the superfamily, but were originally placed within the family Palaeomerycidae.

Suidae
Suidae is a family of artiodactyl mammals which are commonly called pigs, hogs or swine. In addition to numerous fossil species, 18 extant species are currently recognized (or 19 counting domestic pigs and wild boars separately), classified into between four and eight genera. Within this family, the genus ''Sus'' includes the domestic pig, ''Sus scrofa domesticus'' or ''Sus domesticus'', and many species of wild pig from Europe to the Pacific. Other genera include babirusas and warthogs. All suids, or swine, are native to the Old World, ranging from Asia to Europe and Africa. The earliest fossil suids date from the Oligocene epoch in Asia, and their descendants reached Europe during the Miocene. Several fossil species are known and show adaptations to a wide range of different diets, from strict herbivory to possible carrion-eating (in Tetraconodontinae). Physical characteristics Suids belong to the order Artiodactyla, and are generally regarded as the living members of that or ...

Chevrotain
Chevrotains, or mouse-deer, are small even-toed ungulates that make up the family Tragulidae, the only extant members of the infraorder Tragulina. The 10 extant species are placed in three genera, but several species also are known only from fossils. The extant species are found in forests in South and Southeast Asia, with a single species, the water chevrotain, in the rainforests of Central and West Africa. They are solitary or live in pairs, and feed almost exclusively on plant material. Chevrotains are the smallest hoofed mammals in the world. The Asian species weigh between , while the African chevrotain is considerably larger at . With an average length of and an average height of , the Java mouse-deer is the smallest extant (living) ungulate or hoofed mammal, as well as the smallest extant even-toed ungulate. In November 2019, conservation scientists announced that they had photographed silver-backed chevrotains (''Tragulus versicolor'') in a Vietnamese for ...

Rhinoceros
A rhinoceros (; ; ), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae. (It can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea.) Two of the extant species are native to Africa, and three to South and Southeast Asia. Rhinoceroses are some of the largest remaining megafauna: all weigh at least one tonne in adulthood. They have a herbivorous diet, small brains (400–600 g) for mammals of their size, one or two horns, and a thick (1.5–5 cm), protective skin formed from layers of collagen positioned in a lattice structure. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African species of rhinoceros lack teeth at the front of their mouths; they rely instead on their lips to pl ...

Prodeinotherium
''Prodeinotherium'' is an extinct representative of the family Deinotheriidae that lived in Africa, Europe, and Asia in the early and middle Miocene. ''Prodeinotherium'', meaning "before terrible beast", was first named in 1930, but soon after, the only species in it, ''P. hungaricum'', was reassigned to ''Deinotherium''. During the 1970s, however, the two genera were once again separated, with ''Prodeinotherium'' diagnosed to include ''Deinotherium bavaricum'' (=''P. hungaricum''), ''Deinotherium hobleyi'', and ''Deinotherium pentapotamiae'', which were separated based on geographic location. The three species are from Europe, Africa, and Asia, respectively. However, because of usage of few characters to separate them, only one species, ''P. bavaricum'', or many more species, including ''P. cuvieri'', ''P. orlovii'', and ''P. sinense'' may be possible. ''Prodeinotherium'' is one of three genera of the Deinotheriidae, the others being ''Chilgatherium'' from Africa, and ''Deinother ...
