Cenogram of Ulm-Westtangente compared to the Polish Bialowieza National Parc clustering closer to Ulm-Westtangente in the principal component analysis (see Fig. 3). Fossil faunas of the MN2 biozone are also compared to Ulm-Westtangente and their geographic positions are located on a palaeomap (after Rögl 1999). Data for cenograms of fossil faunas are taken from Costeur (2005). Histograms show a comparison of the distribution of species richness expressed as percentages (data used in the PCA, Fig. 3) between Ulm-Westtangente and the Polish temperate forest
