genus having 20% or more complete data. Four main clusters (Fig. 27) are obvious: Ornithomimosauria, Dromaeosauridae, Troodontidae, and Oviraptorosauria, although there is not much separation between Dromaeosauridae and Troodontidae. Two alvarezsaurids grouped together ( Patagonykus and Alvarezsaurus ), but they did not cluster with the other alvarezsaurids ( Mononykus and Shuvuuia ). Oddly, Utahraptor did not group with the other dromaeosaurids (it is instead close to tyrannosaurids). Avialans, especially Archaeopteryx , were closest to the dromaeosaurid cluster. Ornithomimosauria for Chinzorig et al . (2018) likewise showed spatial separation from all other taxa for PC 2 (Fig. 28). A division within Ornithomimosauria is also visible between Ornithomimidae ( Gallimimus , Struthiomimus ,and Ornithomimus )andDeinocheridae ( Garudimimus and Deinocherius ), with Harpymimus grouping with the latter. PC 3 shows similar separation within the group although Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC 411 Figure 3. Biplot of PCA scores (black) and vectors (gray) for Baron’s (2018) data matrix for the Dinosauria taxa with the most complete data. PC 1 accounts for 26.5% of the variance and PC 2 accounts for 17.5% of the variance. Theropods (left) show discontinuity with ornithischians (bottom) and sauropodomorphs (right).
