Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC 427 Figure 43 . Three-dimensional classical MDS applied to Galton and Upchurch’s (2004a) data matrix for “Prosauropoda”. Members of “Prosauropoda” are shown in gray, Shunosaurus in orange, and two generic outgroups in red. Scree plot indicates the first two coordinates account for a majority of the variance. Figure 44. Biplot of PCA scores (black) and vectors (gray) for Galton and Upchurch’s (2004a) data matrix for “Prosauropoda”. PC 1 accounts for 35.8% of the variance and PC 2 accounts for 24.1% of the variance. Outgroups show similar separation as MDS results. Figure 45. PCA scores for Bronzati’s (2017) data matrix for “Prosauropoda”. PC 1 accounts for 37.9% of the variance and PC 2 accounts for 22.9% of the variance. PC 1 separates sauropods (left) from other sauropodomorphs and the outgroup taxa. Outgroup taxa cluster in the upper right, Thecodontosauridae cluster between the outgroup taxa and the “prosauropods”. Figure 46. PCAscores for Bronzati’s (2017) data matrix for Prosauropoda. PC 1 accounts for 37.9% of the variance and PC 3 accounts for 6.2% of the variance. PC 3 distinguishes non-massopod sauropodomorphs (above) from non-sauropod massopods (below).
