Figure 9. Partitions around medoids (PAM) analysis of the Allokotosauria subset dataset in: A) 2 groups and B) 3 groups. The two groups correspond to Allokotosauria (red) and outgroup (green). The three groups correspond to Allokotosauria (red), Sarmatosuchus (green), and other outgroup taxa (blue). the outgroup or with the rhynchosaurids. The hyperodapedontines and the non-hyperodapedontine rhynchosaurids show more distinction between each other in these results than they did when Noteosuchus, Langeronyx, and Eohyosaurus were included. The PAM result with the highest average silhouette value (0.48) is at four groups (Figure 13B): 1) non-hyperodapedontine rhynchosaurids (red), 2) outgroup (green), 3) “basal” rhynchosaurs (blue), and 4) Hyperodapedontinae (yellow). Each of these four groups in PAM have medium to high silhouette widths. The non-hyperodapedontine rhynchosaurs have an average width of 0.42, the hyperodapedontines 0.48, the “basal” rhynchosaurs 0.53, and the outgroup 0.55. When the three problematic taxa were removed, the FANNY result with the highest average silhouette width (0.43) is at three groups. The three groups are the “basal” rhynchosaurs and outgroup (green), the hyperodapedontines (blue), and the non-hyperodapedontine rhynchosaurids (red). E. Proterosuchidae, Erythrosuchidae, and Euparkeriidae The Pearson BDC of the Proterosuchidae and Erythrosuchidae subset (Figure 15A) shows two blocks of positive correlation: Erythrosuchidae and Proterosuchidae, although the Panchet proterosuchid and Fugusuchus hejiapanensis only shared positive correlation with Proterosuchus fergusi. Garjainia madiba only shared positive correlation with Garjainia prima in the erythrosuchid block. Sarmatosuchus otschevi did not share correlation of any kind with any other MCLAIN, CLAUSEN, PEREZ, BEEBE, AND AHTEN Archosauromorph Baraminology 2023 ICC 497
