Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC 419 Figure 18. PCA scores for Carrano et al . ’s (2012) data matrix for Tetanurae. PC 1 accounts for 29.5% of the variance and PC 2 accounts for 19.3% of the variance. Tetanurans include an almost continuous morphoseries consisting of Allosauroidea members (top), Coelurosauria (middle), and Megalosauroidea (last). Tetanurans are separate from non- tetanurans (including Ceratosauria and Coelophysoidea). Two spinosaurids ( Baryonyx and Suchomimus ) are distant from the other tetanurans. Figure 19. PCA scores for Carrano et al . ’s (2012) data matrix for Tetanurae. PC 1 accounts for 29.5% of the variance and PC 3 accounts for 15.6% of the variance. PC 3 separates Allosauroidea members (left) while also distinguishing Megalosauroidea and Coelurosauria clusters. Figure 20 . BDC results for Holtz’s (2004) data matrix of the Tyrannosauroidea subset of basal Tetanurae, as calculated by BDISTMDS (relevance cutoff 0.75). Closed squares indicate significant, positive BDC; open circles indicate significant, negative BDC. Figure 21 . Three-dimensional classical MDS applied to Holtz’s (2004) data matrix for Tyrannosauroidea within basal Tetanurae. Members of Tyrannosauroidea are shown in gray, other tetanurans in orange, and outgroup dark red. Tetanuran outgroups and Tyrannosauroidea form nearly orthogonal ordinations. Scree plot indicates the first axis represents most of the variance.
