Аннотация
The ochotonid faunas of Eurasia and North America from the Oligocene to the present time are reviewed. The pika family (Ochotonidae Thomas 1897) belongs to the order Lagomorpha, which includes five families: Ochotonidae, Mimotonidae Li 1978, Leporidae Fischer 1817 (hares), Palaeolagidae Dice 1929, and Prolagidae Gureev 1960. The family Ochotonidae consists of two subfamilies: Sinolagomyinae Gureev, 1960 and Ochotoninae Thomas, 1897 and comprises a total of 17 genera. Originating in Central Asia at the beginning of the Late Oligocene, pikas flourished during the Late Oligocene. The highest taxonomic diversity of pikas can be found in the Miocene and Pliocene; towards the Pleistocene, the ochotonid fauna declined. Only one genus, Ochotona, remained extant by the end of the Pleistocene. The genus includes a total of 38 known extinct taxa and 28 extant species.
