The study of faunal communities of the past, and how they have changed to become what they are now, is fundamental to the understanding of the changes in ecosystems that we are witnessing and that are coming in the future. In this paper, we present the small mammal assemblage from Grotta del Sambuco (Massa Marittima, Grosseto), belonging to two archaeologic stratigraphic Units, 5 and 6, both dated to Marine Isotope Stage 2. The assemblage from Unit 6 can be defined as "non-analogue", due to the occurrence of the Narrow-headed Vole Lasiopodomys anglicus and the Southern Birch Mouse Sicista subtilis. Non-analogue communities (i.e., with no equivalent in present time) are frequent during Late Pleistocene in the Italian Peninsula. Starting with Grotta del Sambuco, we describe some of the different factors leading to the origins and disappearance of past non-analogue small mammal assemblages in Italy. Climatic changes and the consequent shifts in geographic distributions of the species play a major role in shaping these communities, eventually leading to extirpation and extinction of cold- or continental-adapted species.
