Figure 6. Fuzzy analysis (FANNY) of the “Protorosauria” subset dataset in 2 groups Figure 7. Baraminic distance correlation (BDC) results for the Allokotosauria subset dataset analysis using: A) Pearson correlation coefficient and B) Spearman correlation coefficient. Black squares indicate significant positive correlation, whereas open circles indicate significant negative correlation. Figure 8. 3D multidimensional scaling (MDS) results for the Allokotosauria subset dataset analysis in two views: A and B. Blue represents outgroup taxa and purple represents Allokotosauria. rhynchosaurids, one group includes the outgroup, and the final group includes the “basal” rhynchosaurs. The rhynchosaurid taxa share significant positive correlation. There is negative correlation separating the rhynchosaurids from the outgroup, but there are only instances of negative correlation between the rhynchosaurids and Mesosuchus among the “basal” rhynchosaurs. The Spearman BDC plot for the same taxa (Figure 11D) similarly shows three blocks of positive correlation with negative correlation surrounding the two rhynchosaurid blocks but with no instances of positive or negative correlation between those two blocks. However, two of the blocks this time are made of rhynchosaurid taxa: 1) Hyperodapedontinae and 2) the rest of the rhynchosaurids. The final block of positive correlation consists of the “basal” rhynchosaurs and the outgroup. The MDS results for the rhynchosaur subset excluding the poorly known taxa give deeper insight into the clustering patterns among these species (Figure 12B). The outgroup is again separated from the other groups, but the “basal rhynchosaurs” do not really cluster with MCLAIN, CLAUSEN, PEREZ, BEEBE, AND AHTEN Archosauromorph Baraminology 2023 ICC 496
