Figure 29. 3D multidimensional scaling (MDS) results for the non-paracrocodylomorph Pseudosuchia subset dataset in four views: A, B, C, and D. Colors: Yellow - Ornithosuchidae; Red - Aetosauria; Blue - Gracilisuchidae; Green - Parringtonia; Purple - Ticinosuchus. Scleromochlus (Foffa et al. 2022). As such, we predict that it will fall within the lagerpetid holobaramin in future studies that incorporate newer data. The pterosaurs, as seems to consistently be the case in baraminological analyses (see, for example, Clausen and McLain 2021), were difficult to read. We can see evidence for discontinuity surrounding the group in the 0.29 Pterosauromorpha subset analysis, but not as much as we might expect. This is likely due to the low numbers of characters included in the dataset to set apart pterosaurs from other taxa. The included pterosaurs are all non-pterodactyloid and mainly Triassic forms (with the exception of Rhamphorhynchus, Dimorphodon, and Cacibupteryx). It is not surprising that Rhamphorhynchus does not quite fall close to the other pterosaurs given the lack of other rhamphorhynchids (e.g., Dorygnathus, Scaphognathus) in the 0.29 Pterosauromorpha subset analysis” between “pterosaurs” and “given”.. It is interesting that the 0.29 Pterosauromorpha BDC and MDS results recovered two different groups of Triassic pterosaurs sharing positive correlation: Eudimorphodontoidea and Preondactylia + Dimorphodontidae. The PAM and FANNY results had relatively similar numbers for three- and four-group models (and two and five groups for PAM), and these three and four group models did differentiate these same pterosaur bins. McLain (2022) found evidence for discontinuity between Rhamphorhynchidae and Triassic pterosaurs, which agrees with these results, but he did not find evidence for two Triassic monobaramins. However, the dataset McLain (2022) used (Yang et al. 2022) only included five Triassic pterosaur taxa (Eudimorphodon, Carniadactylus, Raeticodactylus, Austriadactylus, and Preondactylus). Indeed, McLain (2021) used a dataset (Wei et al. 2021) where six Triassic pterosaurs were retained in the analysis (Raeticodactylus, Eudimorphodon, Seazzadactylus, Carniadactylus, MCLAIN, CLAUSEN, PEREZ, BEEBE, AND AHTEN Archosauromorph Baraminology 2023 ICC 514
