Table 3 Taxonomic affinities of the Vitznau Marl coral fauna (= 18 species) to other Valanginian coral assemblages, consisting of a similar number of species or higher (see Appendix Table 6 for assemblages excluded from this evaluation), using the Jaccard index (= number of shared species, divided by total number of species in two localities)
