Title 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
Downloaded 15 times
Description 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.

Title Supplementary Fig. 3. SDD calculated at the locality/species level for the NWE province and the MED province for each chronozone of the early Pliensbachian, after grouping the species according to the volume of their shell
Downloaded 14 times
Description Similarity distance decay calculated at the locality/species level for the NWE province (A-F) and the MED province (G-L) for each chronozone of the early Pliensbachian, after grouping the species according to the volume of their shell (V = ln(volume) in mm3), in order to determine if there is a relationship between shell size and long-distance dispersal. For each province, the lower graphs represent the small species and the upper graphs the large ones. The black lines are the Ordinary Least-Square linear regressions and the SDD rates are the values of their slopes.

Title Supplementary Fig. 5. SDD calculated at the locality/species level for the NWE province and the MED province for each chronozone of the early Pliensbachian, after grouping the species according to the relative whorl height of their shell
Downloaded 13 times
Description Similarity distance decay calculated at the locality/species level for the NWE province (A-F) and the MED province (G-L) for each chronozone of the early Pliensbachian, after grouping the species according to the relative whorl height of their shell (H / D, H = last-whorl height, D = shell diameter), in order to determine whether a relationship between shell shape and long-distance dispersal exists. For each province, the lower graphs represent the most evolute species and the upper graphs the most involute ones. The black lines are the Ordinary Least-Square linear regressions and the SDD rates are the values of their slopes.

Title Supplementary Fig. 7. Morphospaces of early Pliensbachian ammonite species
Downloaded 17 times
Description Morphospaces of early Pliensbachian ammonite species. They correspond to principal component analyses based on the variance-covariance matrices of classical shell parameters (relative height (H / D), relative width (W / D), and relative umbilical diameter (U / D; see Brosse et al. 2013). The convex hulls delimitate species characterizing the NWE province (blue) and the MED province (orange). The MANOVA performed on the PCA scores for each morphospace indicates that there is no significant difference in the shell shape between NWE and MED species.

Description Palaeocoordinates of the 100 studied fossil localities, together with the palaeogeographic distances separating them and the clusters of fossil localities. Four localities were removed compared to the initial dataset of Dommergues et al. (2009), due to their poorly constrained palaeolocations: Ag-CHEL, Bu-KOTE, Gl-JAME and It-TAOR.

Title Supplementary Table 2. Results of Mantel permutation tests between the Sørensen and Simpson dissimilarity matrices and between the Sørensen and nestedness-resultant component matrices
Downloaded 7 times
Description Results of Mantel permutation tests (Mantel 1967; Manly 2007) between the Sørensen and Simpson dissimilarity matrices (upper table) and between the Sørensen and nestedness-resultant component matrices (lower table). All matrices were computed using the package betapart (Baselga and Orme 2012) in R v.3.0.2. (R Development Core Team, 2010). Only localities with at least 4 species, and clusters with at least 7 species and 3 clades were retained in the analyses. Abbreviations: n, number of taxa; N, number of sites; r, correlation coefficient associated to the Mantel tests; p, p-value associated to the Mantel tests calculated using 1000 permutations.

Description Regression statistics for the SDD analyses of early Pliensbachian ammonites of the western Tethys and adjacent areas without null-similarity values and endemic species. At the locality/species and cluster/species levels, only assemblages with at least, respectively 4 species and 7 species were retained in the analyses. Abbreviations: n, number of taxa; N, number of sites; r2, coefficient of determination associated to the linear regressions; p, p-value associated to the linear regressions calculated using 10.000 randomizations; pM, p-value estimating the linear association between D and ln(S) calculated with a Mantel permutation test.
