| Summary: | [EN] The micromammals (orders Rodentia, Insectivora and Lagomorpha) from the cave of Linar site of the end of the upper Pleistocene are here studied for the first time. The fauna comesfrom the following drillings and levels: Drilling A: Levels 3 (15.250 BP) and 4; Drilling B: Level 3 (19.700 BP) and Drilling C: Levels 2, 3 (14.000-15.900 BP) and 4. The list of micromammals of the site is the following: Apodemus sp., Arvicola terrestris, Microtus arvalis-Microtus agrestis, Microtus oeconomus, Microtus lusitanicus, Chionomys nivalis, Clethrionomys glareolus, Sorex araneus, Sorex minutus, Neomys cf. fodiens, Talpa europaea, Erinaceus europaeus and cf. Lepus sp. All these taxa live nowadays in the Cantabrian Region except: Sorex araneus which distribution in the Iberian Peninsula has reduced to the north of Catalonia and Microtus oeconomus that is not in Spain but in northern Euroasiatic regions. The most abundant taxa in almost all the drillings and levels are: Microtus arvalis-Microtus agrestis and Microtus oeconomus, with a mean of percentage very similar of 30,6 % and 30,3 % respectively for all the site. After these taxa, the most abundant species in decreasing order is Arvicola terrestris with a mean of percentage of 19,8 % for all the site. The paleoenvironmental study of the faunal assemblage suggests a mainly open and humid environment and a cold climate. [ES] En este trabajo se estudian por primera vez los micromamíferos (órdenes Rodentia, Insectivora y Lagomorpha) del yacimiento del final del Pleistoceno superior de la cueva de El Linar (Cantabria, norte de España). La fauna procede de los siguientes sondeos y niveles: sondeo A: niveles 3 (15.250 BP) y 4; sondeo B: nivel 3 (19.700 BP) y sondeo C: niveles 2, 3 (14.000-15.900 BP) y 4. La relación de micromamíferos del yacimiento es la siguiente: Apodemus sp., Arvicola terrestris, Microtus arvalis-Microtus agrestis, Microtus oeconomus, Microtus lusitanicus, Chionomys nivalis, Clethrionomys glareolus, Sorex araneus, Sorex minutus, Neomys cf. fodiens, Talpa ...
