Figure 10. Fuzzy analysis (FANNY) of the Allokotosauria subset dataset in: A) 2 groups and B) 3 groups. The two groups correspond to Allokotosauria (red) and outgroup + Pamelaria (green). The three groups correspond to Azendohsauridae (red), outgroup (green), and Trilophosauridae (blue). taxon in the analysis. In the Spearman BDC (Figure 15B), there was a clear division between the two groups Erythrosuchidae and Proterosuchidae, but Sarmatosuchus ostchevi again correlated with only itself. The two blocks of positive correlation shared only negative correlation or no correlation between them. When we added the euparkeriid Euparkeria capensis and the possible euparkeriid Osmolskina czatkowicensis, the two blocks were still clear (Supplemental Figure 4). Euparkeria did not share positive correlation with any other taxon, but it shared negative correlation with most erythrosuchids and the Panchet proterosuchid. Surprisingly, Osmolskina showed positive correlation with some erythrosuchids and not Euparkeria. In the MDS results (Figure 16), both groups were clearly separated, with Sarmatosuchus ostchevi grouping with the proterosuchids. We also ran it with Euparkeria capensis and Osmolskina czatkoviensis, which made the proterosuchid and erythrosuchid clustered less clear (Supplemental Figure 5). As with the BDC results (Supplemental Figure 4), Euparkeria did not cluster with any other taxa, whereas Osmolskina clusters with the erythrosuchids. When we put the data through PAM (Figure 17), the highest average silhouette values were at two groups (0.41) and three groups (0.33).
