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, in the 1990s, genetic evidence 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 ... [...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 skunk *** ''Spilogale gr ...

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 clas ...

Palaeomephitis
''Palaeomephitis steinheimensis'' is an extinct species of musteloid, possibly a mephitid (skunk), from the Miocene epoch of Europe. 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. However, Geraads and Spassov (2016) were uncertain it in fact had this expanded recess, since that area of the skull is imperfectly preserved. Due to this and other factors, such as it differing from Mephitidae in some characters, these authors considered the mephitid affinities of ''Palaeomephitis'' doubtful. Taxonomy In its traditional skunk classification, ''Palaeomephitis'' is considered to stand close ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Pandas
The red panda (''Ailurus fulgens''), also known as the lesser panda, is a small mammal native to the eastern Himalayas and southwestern China. It has dense reddish-brown fur with a black belly and legs, white-lined ears, a mostly white muzzle and a ringed tail. Its head-to-body length is with a tail, and it weighs between . It is well adapted to climbing due to its flexible joints and curved semi-retractile claws. The red panda was formally described in 1825. The two currently recognised subspecies, the Himalayan and the Chinese red panda, genetically diverged about 250,000 years ago. The red panda's place on the evolutionary tree has been debated, but modern genetic evidence places it in close affinity with raccoons, weasels, and skunks. It is not closely related to the giant panda, which is a bear, though both possess elongated wrist bones or " false thumbs" used for grasping bamboo. The evolutionary lineage of the red panda ( Ailuridae) stretches back around , as ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
