Data were obtained from selected localities in Spain, France and Italy and mammalian records were ordered in nine successive time intervals. We used body mass, estimated from dental and post-cranial measurements, to represent body-size. Four major immigration and/or faunal turnover episodes took place in the Northwestern Mediterranean area from late Miocene to Holocene: the Ruscinian turnover, the Equus-elephant event, the “Wolf” event, and the Galerian turnover. Significant body-size changes occurred in at least two of these episodes. The emerging pattern suggests that changes in the mean body-size of groups was mainly the result of migration of new species of larger size. However, variations in body-size within evolutionary lines were coincident with periods of major climatic change, suggesting that climate, too, played an important role in body-size change. The data did not provide evidence for the existence of a common pattern of size change in the 12 mammalian families studied. The pattern of body-size distribution remained constant throughout the late Turolian and Ruscinian (around 6 to 4 Ma), probably due to climate stability and the predominance of subtropical conditions. A significant change in body-size occurred during the early Villafranchian (around 3 Ma) and at the beginning of the Galerian (around 1 Ma).
