Abstract
At the “International Symposium on Mammalian Biostratigraphy and Paleo-ecology of the European Paleogene” in 1987 in Mainz, Néstor Mayo and I have presented a biozonation of the Lower Freshwater Molasse based on mammals (see Engesser and Mayo, 1987). In this biozonation the Lower Freshwater Molasse was subdivided into 18 mammal zones. In contrast to previous zonations, complete mammal faunas were used, not only one or two families. These zones are based on the evolutionary level of well known evolutionary lines, the first and the last record of certain taxa, and on typical associations. Each zone is defined by a so-called “reference fauna.” In addition, as many as possible molasse faunas of about the same age were integrated into each zone.
