Erdei, B.; Bruch, A. A.: A climate analysis of Late Oligocene (Egerian) macrofloras from Hungary

Naturally, the more NLRs the analysis is based on the more reliable output is resulted. We determined a minimum number of taxa as 12 needed for a reliable climate estimate. In the Eger-Wind flora the three flora levels were calculated using three separate and one combined datasets, causing two data sets with lower number of NLR taxa (Eger 1-8, Eger 2-10 taxa). It must be noted, however, that in the case of older (Palaeogene) floras, the proper identification of taxa and their NLRs on the species or genus level is limited to a higher degree. RESULTS AND DISCUSSION The climate variables for the three flora levels of the Eger-Wind assemblage were calculated using both separate and combined datasets (Table 3). Calculated coexistence intervals are showed by Figure 3. The lower, middle and upper levels Table 3.
