Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC 418 Figure 17. Biplot of PCA scores for Holtz et al . ’s (2004) data matrix for basal Tetanurae. PC 1 accounts for 25.2% of the variance and PC 2 accounts for 18.8% of the variance. Four main clusters are evident: Tyrannosauroidea (blue circle), non-tyrannosauroid Coelurosauria (yellow), non-coelurosaur Tetanurae (red), and non-tetanurans (black). PCArevealed several large morphological divisions, not visible to BDIST, including: (1) a Tyrannosauroidea series; Maniraptoriformes grouped together with smaller clusters of Dromaeosauridae (2), Ornithomimosauria (3), a combined Troodontidae and Oviraptorosauria group (4), and scattered Avialae (black triangles). Non-coelurosaur tetanurans ordinate as a morphoseries toward the right.
