Studies of mammal assemblages for the European MIS 3 have focused on a regionalization using presence-absence data and traditional cluster analysis. Although this approach has revealed mammal assemblages with no modern analogs, it can easily miss two important dynamical aspects of the MIS 3 assemblages, namely, transitional regions and faunal mixtures. We revisited this regionalization using a complementary approach based on the study of quantitative data for ungulate species. The main aim of this work is to evaluate whether the MIS 3 climatic oscillations led to a mixture of faunas or a latitudinal gradient in faunal composition, as well as to identify indicator species for different areas in ungulate mammal paleoassemblages of Western Europe.
