Diversity, palaeoecology and palaeoenvironmental significance of the Eocene chondrichthyan assemblages of the Bolca Lagerstätte, Italy

Table S1. Sørensen-Dice similarity values measuring the similarity between two biological communities based on presence/absence data (Table S2). Higher values indicate high similarity.<br>Table S2. Occurrences of Eocene chondrichthyan fishes in the Boreal and Tethyan localities used for comparative analyses. For each assemblage ‘1’ indicates the presence of the taxon, ‘0’ indicates its absence.
