Aletomeryx
''Aletomeryx'' is an extinct genus of Artiodactyla, of the family Dromomerycidae, endemic to North America from the early Miocene epoch (Hemingfordian stage) 20.6—16.3 Annum, Ma, existing for approximately . Taxonomy ''Aletomeryx'' was named by Lull (1920). It is the type genus of Aletomerycinae, Aletomerycini. It was assigned to Dromomerycidae by Lull (1920) and Janis and Manning (1998); and to Aletomerycini by Prothero and Liter (2007).D. R. Prothero and M. R. Liter. 2007. Family Palaeomerycidae. in D. R.

Dromomerycidae
The Dromomerycidae is an extinct family of Neogene ruminants belonging to the infraorder Pecora. Dromomerycids, known by two subfamilies, were endemic to North America from the later early Miocene up to the early Pliocene (~5 Ma), leaving no descendants. Dromomerycidae has a long history of uncertain taxonomic affiliations due to its superficial resemblances with the Eurasian Neogene Palaeomerycidae and were traditionally classified as subfamilies within the family. However, recent research differentiates the dromomerycids from the Giraffomorpha (Giraffoidea and Palaeomerycoidea) by the lack of sutures on the skull roof that typically make up the ossicones of the later clade. The similar resemblances of the appendages therefore could be the result of parallel evolution. The dromomerycids are characterized by unbranched and nondeciduous appendages above the orbits of the eyes. These traits may have been typically characteristic of males but appear to have been present in both ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeomerycidae
The Palaeomerycidae are an extinct family of ruminants in the order Artiodactyla. Palaeomerycids lived in North America, Europe, Africa and Asia from 33 to 4.9 million years ago (from the Late Eocene to Pliocene epochs), existing for about 28 million years; one species was also reported from South America, but its identity as a palaeomerycid was subsequently disputed. Specimens of '' Amphitragulus'', the earliest known genus, have been found in Aragon (Spain), Ronheim (Germany), Sardinia (Italy), France, and Kazakhstan and range from 33 to 15.97 million years old. Fossils of '' Lagomeryx'' and ''Palaeomeryx feignouxi'' were recovered in Germany and Slovakia from the Middle Eocene. The oldest known North American specimen, '' Barbouromeryx'', was discovered in Scotts Bluff, Nebraska, and estimated at 23.03 million years old. Palaeomerycids such as ''Cranioceras'' and other Dromomerycinae continued to live in North America until the early Pliocene. Description Palaeomerycids w ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Miocene Artiodactyla
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Artiodactyla
The even-toed ungulates (Artiodactyla , ) are ungulates—hoofed animals—which bear weight equally on two (an even number) of their five toes: the third and fourth. The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, odd-toed ungulates bear weight on an odd number of the five toes. Another difference between the two is that many other even-toed ungulates (with the exception of Suina) digest plant cellulose in one or more stomach chambers rather than in their intestine as the odd-toed ungulates do. Cetaceans (whales, dolphins, and porpoises) evolved from even-toed ungulates, and are therefore often classified under the same taxonomic branch because a species cannot outgrow its evolutionary ancestry; some modern taxonomists combine the two under the name Cetartiodactyla , while others opt to include cetaceans in the already-existing Artiodactyla. The roughly 270 land-based even-toed ungulate species include pigs, peccaries, hippopo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
