Promephitis
''Promephitis'' is an extinct genus of mephitid, of which several species have been described from the Miocene and early Pliocene of Europe and Asia. Characteristics The fossil remains of the ''Promephitis'' species, like all members of the skunk family (Mephitidae), have a significant extension of epitympanic recess, a chamber of the middle ear, into the region of mastoid and squamous parts of the temporal bones. This extension is recognizable as an inflated bulge on the lateral wall of the skull over the mastoid. In addition, skunks have specific characteristics of the teeth, especially the molars, which distinguish them from other carnivora. The genus ''Promephitis'' also shows a distinctive structure of the premolar tooth P4 as well as a very small P2, through which they are distinguishable from other genera. Distribution and temporal classification Species of ''Promephitis'' ranged widely in Eurasia, and fossils have been found both in Europe and in Asia. They are classi ...

Palaeomephitis
''Palaeomephitis steinheimensis'' is an extinct species of mephitid of the Miocene epoch in Europe. It is the earliest known species of the family Mephitidae. Description ''Palaeomephitis steinheimensis'' was described by Jäger in 1839 from a well-preserved cranium found in Steinheim am Albuch in Baden-Württemberg, southern Germany. Subsequently, different authors considered it to represent a viverrid or a leptarctine mustelid. It was placed in the Mephitinae (now considered to be a distinct family) by Wolsan in 1999, on the evidence of its having an extended epitympanic recess to the middle ear. Taxonomy Within the skunks, ''Palaeomephitis'' is considered to stand close to the two extant species of stink badger (''Mydaus'') and the several extinct species of ''Promephitis ''Promephitis'' is an extinct genus of mephitid, of which several species have been described from the Miocene and early Pliocene of Europe and Asia.

Mephitidae
Mephitidae is a family of mammals comprising the skunks and stink badgers. They are noted for the great development of their anal scent glands, which they use to deter predators. Skunks were formerly classified as a subfamily of the Mustelidae (the weasel family); however, recent genetic evidence has caused skunks to be treated as a separate family. Similarly, the stink badgers had been classified with badgers, but genetic evidence shows they share a more recent common ancestor with skunks, so they are now included in the skunk family. A 2017 study using retroposon markers indicated that they are most closely related to the Ailuridae (red pandas and allies) and Procyonidae (raccoons and allies). There are twelve extant species of mephitids in four genera: ''Conepatus'' (hog-nosed skunks, four species); '' Mephitis'' (the hooded and striped skunks, two species); ''Mydaus'' (stink badgers, two species); and ''Spilogale'' (spotted skunks, four species). The two stink badgers in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skunk
Skunks are mammals in the family Mephitidae. They are known for their ability to spray a liquid with a strong, unpleasant scent from their anal glands. Different species of skunk vary in appearance from black-and-white to brown, cream or ginger colored, but all have warning coloration. While related to polecats and other members of the weasel family, skunks have as their closest relatives the Old World stink badgers. Taxonomy In alphabetical order, the living species of skunks are: * Family Mephitidae ** Genus: ''Conepatus'' *** ''Conepatus chinga'' – Molina's hog-nosed skunk *** ''Conepatus humboldtii'' – Humboldt's hog-nosed skunk *** ''Conepatus leuconotus'' – American hog-nosed skunk *** ''Conepatus semistriatus'' – striped hog-nosed skunk ** Genus: '' Mephitis'' *** ''Mephitis macroura'' – hooded skunk *** ''Mephitis mephitis'' – striped skunk ** Genus: ''Spilogale'' *** ''Spilogale angustifrons'' – southern spotted s ...

Miocene
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.

Premolar
The premolars, also called premolar teeth, or bicuspids, are transitional teeth located between the canine and molar teeth. In humans, there are two premolars per quadrant in the permanent set of teeth, making eight premolars total in the mouth. They have at least two cusps. Premolars can be considered transitional teeth during chewing, or mastication. They have properties of both the canines, that lie anterior and molars that lie posterior, and so food can be transferred from the canines to the premolars and finally to the molars for grinding, instead of directly from the canines to the molars. Human anatomy The premolars in humans are the maxillary first premolar, maxillary second premolar, mandibular first premolar, and the mandibular second premolar. Premolar teeth by definition are permanent teeth distal to the canines, preceded by deciduous molars. Morphology There is always one large buccal cusp, especially so in the mandibular first premolar. The lower second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stink Badger
Stink badgers, also known as false badgers are a genus (''Mydaus'') of the skunk family of carnivorans, the Mephitidae. They resemble the better-known members of the family Mustelidae also termed 'badgers' (which are themselves a polyphyletic group). There are only two extant species – the Palawan stink badger or ''pantot'' (''M. marchei''), and the Sunda stink badger or ''teledu'' (''M. javanensis''). They live only on the western islands of the Greater Sunda Islands: Sumatra, Java, Borneo in Indonesia, Malaysia and Brunei and (in the case of the Palawan stink badger) on the Philippine island of Palawan; as well as many other smaller islands in the region. Stink badgers are named for their resemblance to other badgers and for the foul-smelling secretions that they expel from anal glands in self-defense (which is stronger in the Sunda species).

Jean Albert Gaudry
Jean Albert Gaudry (16 September 1827 – 27 November 1908) was a French geologist and palaeontologist. He was born at St Germain-en-Laye, and was educated at the Catholic Collège Stanislas de Paris. He was a notable proponent of theistic evolution.Buffetaut, Éric. (1987). ''A Short History of Vertebrate Palaeontology''. Croom Helm. p. 117 Career At the age of twenty-five he made explorations in Cyprus and Greece, residing in the latter country from 1855 to 1860. He then investigated the rich deposit of fossil vertebrata at Pikermi and brought to light a remarkable mammalian fauna, Miocene in age, and intermediate in its forms between European, Asiatic and African types. He also published an account of the geology of the island of Cyprus (''Mém. Soc. Géol. de France'', 1862). In 1853, while still in Cyprus, he was appointed assistant to Alcide Dessalines d'Orbigny, A d'Orbigny, who was the first to hold the chair of palaeontology in the museum of natural history at Paris.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
