Aplodontidae
The family Aplodontiidae also known as Aplodontidae, Haplodontiidae or Haploodontini is traditionally classified as the sole extant family of the suborder Protrogomorpha. It may be the sister family of the Sciuridae. There are fossils from the Oligocene until Miocene in Asia, from Oligocene in Europe and from the Oligocene until the present in North America, where there is the only living species: the mountain beaver (''Aplodontia rufa''). Systematics It includes the following genera: * '' Aplodontia'' Richardson, 1829 * †'' Altasciurus '' Korth, 2019 * †'' Ameniscomys'' Dehm, 1950 * †'' Ansomys'' Qiu, 1987 * †'' Dakotallomys'' Tedrow and Korth, 1999 * †'' Disallomys'' Korth, 2009 * †'' Ephemeromys'' Wang & Heissig, 1984 * †'' Haplomys'' Miller and Gidley, 1918 * †'' Leptoromys'' Tedrow and Korth, 1997 * †'' Liodontia'' Miller and Gidley, 1918 * †'' Meniscomys'' Cope, 1879 * †''Niglarodon'' Black, 1961 * †''Ninamys'' Vianey-Liaud, Rodrigues & Marivaux, ...

Aplodontia
The mountain beaver (''Aplodontia rufa'')Other names include mountain boomer, ground bear, giant mole, gehalis, lesser sasquatch, sewellel, suwellel, showhurll, showtl, and showte, as well as a number of Chinookan and other Native American terms; "mountain boomer" is a misnomer, and the animal does not make the characteristic tail slapping sound of the true beaver species. See Carraway and Verts, 1993. Lewis and Clark originally called the animal "sewellel", a misunderstanding of the Chinook word "she-wal-lal", the name for garments made from the skin of the creature. See Borrecco and Anderson, 1980. is a North American rodent. It is the only living member of its genus, ''Aplodontia'', and family, Aplodontiidae. It should not be confused with true North American and Eurasian beavers, to which it is not closely related, being more closely related to squirrels. There are 7 subspecies of mountain beavers, 6 of which are found in California and 3 of which are endemic to the state. S ...

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
