Aplodontiid
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, 20 ...

Oligocene
The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period that 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 Ancient Greek (''olígos'') 'few' and (''kainós'') 'new', and refers to the sparsity of Neontology, extant forms of Mollusca, 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 chang ...
