Supplementary Fig. 2. Correspondence analyses calculated made at the species/locality and clade/cluster levels for the western Tethys for each chronozone of the early Pliensbachian

Correspondence analyses made at the species/locality (A-C) and clade/cluster (D-E) levels for the western Tethys for each chronozone of the early Pliensbachian, in order to determine if the biogeographical partitioning detected at the species level still exists at the clade level. The polygons represent the 95% convex hull of the MED assemblages (in orange) and NWE assemblages (in blue). Eigenvalues are indicated for each axes. Only localities with at least 4 species and clusters with at least 3 clades are considered in these analyses.
