Non-hadrosaurid Hadrosauriformes Holobaramin? Horner et al. (2004) Negative correlation or no correlation with other taxa (BDC). No clustering with other taxa (MDS/PCA). Cruzado-Caballero and Powell (2017) No clustering with other taxa (PCA). McDonald (2012) No clustering with non- hadrosauriform taxa (PCA). Madzia et al. (2017) No clustering with non- hadrosauriform taxa (PCA). Norman (2004) No clustering with other taxa (MDS/PCA). Horner et al. (2004) Members share positive correlation (BDC). Members cluster together (MDS/PCA). Cruzado-Caballero and Powell (2017) Members cluster/make a series (PCA). McDonald (2012) Members cluster/make a series (PCA). Madzia et al. (2017) Members cluster/make a series (PCA). Norman (2004) Members cluster/make a series (MDS/PCA). This group shows some evidence for internal discontinuity, but at the same time it also shows evidence for continuity with hadrosaurids. Most analyses that show evidence for continuity with hadrosaurids are analyses containing a larger iguanodont outgroup. As expected, such analyses would highlight differences between "derived" and "basal" iguanodonts more than the differences between various "derived" iguanodonts. On the other hand, several PCA plots show hadrosauriforms in a series with the "basal" members on one end and hadrosaurids on the other. This might mean that they are a single baramin, and that this trajectory indicates diversification within that group. Alternatively, they might just be different baramins along a similar morphological trajectory. More studies will be needed to determine how many holobaramins are represented. Saurolophinae Holobaramin Horner et al. (2004) No clustering with other taxa (PCA). Cruzado-Caballero and Powell (2017) No clustering with other taxa (PCA). Horner et al. (2004) Members share positive correlation (BDC). Members cluster together (MDS/PCA). Cruzado-Caballero and Powell (2017) Members cluster together (PCA). Alternatively, Hadrosauridae may be a holobaramin containing Saurolophinae and Lambeosaurinae as monobaramins. PC 1/PC 2 of Cruzado-Caballero and Powell (2017) separate out two groups of saurolophines: 1) Kritosaurini + Brachysaurolophini and 2) Edmontosaurini + Saurolophini + Lophorhothon. The aralosaurinin lambeosaurine Aralosaurus clusters with saurolophine group 1. Hadrosaurus is not clustered with the saurolophines at all. Lambeosaurinae Holobaramin Horner et al. (2004) No clustering with other taxa (PCA). Cruzado-Caballero and Powell (2017) No clustering with other taxa (PCA). Horner et al. (2004) Members share positive correlation (BDC). Members cluster together (MDS/PCA). Cruzado-Caballero and Powell (2017) Members cluster together (PCA). Alternatively, Hadrosauridae may be a holobaramin containing Saurolophinae and Lambeosaurinae as monobaramins. Aralosaurus , a lambeosaurine, clusters with saurolophines in the PCA of Cruzado- Caballero and Powell (2017). Pachycephalosauria Holobaramin Maryańska et al. (2004) Negative correlation or no correlation with outgroup taxa (BDC). No clustering with outgroup taxa (MDS/PCA). Schott (2011) No clustering with other taxa (PCA). Schott (2011) Members form a series (PCA). Although the Maryańska et al. (2004) results seem to show separation between pachycephalosaurids and "homalocephalids", the Schott (2011) show that this separation is unfounded. Many paleontologists suspect that pachycephalosaurs with flat skulls are probably juveniles (as evidenced by the proposed Dracorex - Stygimoloch - Pachycephalosaurus ontogenetic series). 455 Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC
