In this work we study the micromammal associations of five new sites from the basin of Calatayud: Viluena, Torralba de Ribota 8, Monton, Armantes 14 and Belmonte. In the first four sites we have recognised the evolved species lineage of Megacricetodon primitivus-collongensis-crusafonti of the Middle Miocene that have allowed us to place them biostratigraphically with accuracy. The oldest site is Viluena, with Megacricetodon primitivus which is a characteristic species of the C y D1 zones corresponding respectively to the Lower and Middle Aragonian. The association of Megacriceton primitivus-collongensis and Fahlbuschia koenigswaldi in Torralba de Ribota 8 is characteristic of the D zone of the Middle Aragonian. In Monton we found the transitional taxon of Megacricetodon collongensis-crusafonti which is characteristic of the F and G1 zones of the Upper Aragonian. In Armantes 14 there is the species Megacricetodon crusafonti that is characteristic of the G2 zone of the Upper Aragonian. Finally in the Belmonte site, the presence of the muridae Progonomys hispanicus, indicates its age of the Upper Vallesian, in the zone J that is characterized by that species. From a paleoenvironmental and paleoclimatic point of view, the presence in the sites of Viluena, Torralba de Ribota 8 and Monton of the terrestrial squirrel of the genus Heteroxerus, and some gliridae of the genus Microdyromys which are not related with a wet climate, and the capacity of this last genus and also of the cricetid genus Fahlbuschia to endure high temperatures, suggest an open country environment and a climate relatively dry and warm during the most part of the Lower and Middle Aragonian and the lower part of the Upper Aragonian as was pointed out in other areas (Daams et al., 1988; Daams & van der Meulen, 1984; van der Meulen & Daams, 1992). In the Upper Aragonian faunal association of Armantes 14, it appears a gliridae of the genus Muscardinus that is considered characteristic of a humid climate, and there are no terrestrial squirrels. This is in agreement with the suggestion made by Daams et al. (op.cit.) that this age was relatively wetter than the former one. There is a faunal micromammal change between the Middle and the Upper Miocene, evident in the faunal association of the Upper Vallesian site of Belmonte in which there are no anyone of the cricetidae that were characteristic of the Middle Miocene but it appears the first muridae represented by the genus Progonomys. This has been interpreted as a climatic change towards relatively drier conditions, that went on during all the Upper Miocene, and also relatively colder, according to Daams et al. (op. cit.).
