The quantitative and qualitative composition, and the general diversity of the micromammalian faunas (Rodentia, Lagomorpha, Insectivora and Chiroptera) from 16 sedimentary fluvial-lacustrine sites from the Guadix-Baza basin, of ages extending from the Late Miocene until the Middle Pleistocene, is analised. The paleoecological and paleoclimatic interpretation of the data obtained in this analysis is the following: The high quantitative and qualitative change, and the relative decrease of the diversity that can be observed in the micromammal faunas from Granada at the beginning of the Villafranchian, seems to be related with an increase of the relative humidity and climatic cooling as regards to the Ruscinian. The relative increase of the diversity in the Middle Pleistocene, indicates a relative more temperate climate than that of the Lower Pleistocene.
