METHOD In order to estimate quantitatively palaeoclimate variables the "Coexistence Approach" (CA) established by MOSBRUGGER and UTESCHER (1997) was adopted. The starting point of the method is the presumption that the climatic requirements of particular fossil taxa is the most comparable with that of its modern "nearest living relative" (NLR). The method aims to describe in terms of climate variables a coexistence interval in which the most NLRs are able to exist. This evaluation is supported by a database comprising the NLRs (and their climatic requirements) of more than 3,000 fossil taxa of the Tertiary. In this paper we estimated four climate variables, i.e. the mean annual temperature (MAT), mean temperature of the warmest (WMT) and coldest month (CMT), and mean annual precipitation (MAP).
