| Summary: | Abstract: The Sierra of Atapuerca, near Burgos (Spain), is a karstic complex where anteneandertalian human remains were found in the filling called "Sima de los Huesos". We have found some faunas of small mammals in this filling and in other fillings located in the area called "Trinchera of Atapuerca": "Gran Dolina" and "Tres Simas complex". All these faunas of small mammals, the preliminary study of which we make here, can be situated in the Middle Pleistocene. Among them, we recognize at least two different faunal associations mainly belonging to the Arvicolidae: I) One faunal group is that of the lower stratigraphic levels of the "Gran Dolina" filling and is characterized by the following species: Pilymys gregaloides-arvalidens, Microtus brecciensis, Pliomys episcopalis, Mimomys savini and Arvicola chalinei. It can be placed in the phases Nagyharsanyhegy/Templomhegy of the Biharian. II) The other faunal group is that of the upper stratigraphic level of the "Gran Dolina" filling and those of the "Tres Simas complex" and is characterized by the following species: Pitymys subterraneus, Microtus arvalis-agrestis, Microtus brecciensis, Pliomys lenki and Arvicola sp. of large size. It may be dated to the last phases of the Biharian (Versteszzöllös/Uppony) or lower Otdenburgian. Other species of rodents recovered in Atapuerca are Allocricetus bursae, Eliomys quercinus and Apodemus sp., present in almost all the localities, Marmota marmota in some levels of faunal groups I and II, and Hystrix cf. vinogradovi in faunal group II. In Atapuerca faunas of the beginning of the Middle Pleistocene (phases Nagyharsanyhegy/Templomhegy of the Biharian) are found for the first time in Spain as well as a faunal sequence with at least two different faunal associations which covers a period between those phases of the Biharian until the last phases of the Biharian or the lower Oldenburgian. Resumen: La Sierra de Atapuerca, cerca de Burgos (España), es un complejo kárstico donde se encontraron restos humanos anteneandertalienses ...
