Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC 437 Figure 76. Biplot of PCAscores (black) and vectors (gray) for McDonald’s (2012) data matrix for Iguanodontia. PC 1 accounts for 62.8% of the variance and PC 2 accounts for 9.2% of the variance. PC 1 separates non- hadrosauriform Iguanodontia (left) from Hadrosauriformes (right). PC 2 separates the non-dryomorph iguanodonts (top) from the dryomorphs (bottom) among the series on the left, and it separates three groups on the right: 1) non-hadrosauroid Hadrosauriformes + Altirhinus (bottom), 2) non-hadrosaurid Hadrosauroidea (middle), and 3) Hadrosauridae (top). Figure 77. Biplot of PCAscores (black) and vectors (gray) for McDonald’s (2012) data matrix for Iguanodontia. PC 1 accounts for 62.8% of the variance and PC 3 accounts for 6.8% of the variance. PC 3 separated “basal” Hadrosauriformes (traditional Iguanodontidae) from the other taxa. Figure 78 . BDC results for Horner et al.’s (2004) data matrix of Hadrosauridae, as calculated by BDISTMDS (relevance cutoff 0.75). Closed squares indicate significant, positive BDC; open circles indicate significant, negative BDC. Figure 79. Three-dimensional classical MDS applied to Horner et al.’s (2004) data matrix for Hadrosauridae. Members of Hadrosauridae are shown in gray, with outgroups Iguanodon , Probactrosaurus , Protohadros , Eolambia , Telmatosaurus , and Lophorhothon (bottom center) shown in orange. Composite outgroup is dark red. Deeper separation within Hadrosauridae (gray) is suggested, though not conclusive. Scree plot suggests the first two axes represent most of the variation.
