The matrix for Stegosauria consisted of 10 taxa and 55 characters. After filtering at 0.80 character relevance cutoff we used 22 characters to calculate baraminic distances. The matrix for Ankylosauria consisted of 24 taxa and 63 characters. After filtering at 0.95 character relevance cutoff we used 13 characters to calculate baraminic distances. The matrix for “basal” Ornithopoda consisted of 12 taxa and 54 characters. After filtering at 0.80 character relevance cutoff we used 22 characters to calculate baraminic distances. The matrix for “basal” Iguanodontia consisted of 17 taxa and 67 characters. After filtering at 0.95 character relevance cutoff we used 14 characters to calculate baraminic distances. The matrix for Hadrosauridae consisted of 21 taxa and 105 characters. After filtering at 0.75 character relevance cutoff we used 58 characters to calculate baraminic distances. The matrix for Pachycephalosauridae consisted of 10 taxa and 35 characters. After filtering at 0.8 character relevance cutoff we used 28 characters to calculate baraminic distances. The matrix for “basal” Ceratopsia consisted of 12 taxa and 148 characters. After filtering at 0.95 character relevance cutoff we used 26 characters to calculate baraminic distances. The matrix for Ceratopsidae consisted of 16 taxa and 73 characters. After filtering at 0.75 character relevance cutoff we used 59 characters to calculate baraminic distances. Matrices published since 2004 had greater numbers of taxa and character variables. These matrices were almost exclusively analyzed with PCA. Two groups were also analyzed with BDC (Ceratosauria and Sauropodomorpha) in order to compare with PCA results. Unless otherwise stated, matrices include culled datasets where taxa with less than 50% of their characters were removed; all taxa were analyzed in several small matrices. As with PCA analyses of the 2004 matrices, missing data was replaced with a probabilistic replacement routine. Dinosaur groups, and matrices, included the following: The Dinosauria matrix consisted of 452 characters for 126 taxa (Baron 2018). We examined both the complete data set in addition to only the 36 taxa with at least 50% of their character states known. The matrix for “basal” Saurischia consisted of 315 characters for 40 taxa (Nesbitt et al . 2009). We examined the 30 taxa with at least 50% of their character states known. The matrix for Abelisauroidea consisted of 206 characters for 24 taxa (Brissón Egli, F. et al . 2016). We examined all 24 taxa with PCA. BDC was filtered at the 0.75 character relevance cutoff. The matrix for basal Tetanurae consisted of 351 characters for 58 taxa (Carrano et al . 2012). We examined the 27 taxa with at least 50% of their character states known. The matrix for Tyrannosauroidea consisted of 249 characters for 33 taxa (Brusatte and Carr 2016). We examined the 21 taxa with at least 50% of their character states known. The matrix for Ornithomimosauria consisted of 568 characters for 98 taxa (Chinzorig et al . 2018). We examined the 37 taxa with at least 50% of their character states known. The matrix for Therizinosauria consisted of 348 characters for 76 taxa (Zanno 2010). We examined both the full dataset and the 26 taxa with at least 50% of their character states known. We analyzed a Maniraptoran matrix in place of Weishampel’s Oviraptorosauria. The matrix consisted of 560 characters for 132 taxa (Foth and Rauhut 2017). We examined both the complete dataset and the 46 taxa with at least 50% of their character states known. The matrix for “basal” Sauropodomorpha consisted of 375 characters for 58 taxa (Bronzati 2017). We examined the 28 taxa with at least 50% of their character states known. Another matrix for “basal” Sauropodomorpha consisted of 370 characters for 55 taxa (Otero et al . , 2015). We examined the 32 taxa with at least 50% of their character states known for PCA. BDC was filtered at the 0.75 character relevance cutoff. The matrix for basal Thyreophora consisted of 227 characters for 49 taxa (Breeden 2016). We examined the 27 taxa with at least 50% of their character states known. The matrix for Stegosauria consisted of 91 characters for 22 taxa (Raven and Maidment 2017). We examined all 22 taxa. The matrix for Ankylosauria consisted of 178 characters for 55 taxa (Zheng 2018). We examined the 21 taxa with at least 50% of their character states known. The matrix for “basal” Ornithopoda consisted of 135 characters for 69 taxa (Madzia 2017). We examined the 26 taxa with at least 50% of their character states known. The matrix for “basal” Iguanodontia consisted of 134 characters for 67 taxa (McDonald 2012). We examined the 26 taxa with at least 50% of their character states known. The matrix for Hadrosauridae consisted of 346 characters for 58 taxa (Cruzado-Caballero 2017). We examined all 58 taxa. The matrix for Pachycephalosauridae consisted of 48 characters for 17 taxa (Schott 2011). We examined all 17 taxa. The matrix for “basal” Ceratopsia consisted of 381 characters for 71 taxa (Han 2017). We examined the 40 taxa with at least 50% of their character states known. The matrix for Ceratopsidae 152 characters for 29 taxa (Fry 2015). We examined all 29 taxa. RESULTS Results are described by taxonomic group, first for the saurischians and then ornithischians. Analyses included BDC, MDS, and PCA for each group. PCA for the Dinosauria was performed to better understand the overall relationships of the new Ornithoscelida (Ornithischia and Theropoda) to Saurischia (Sauropodomorpha and Herrerasauridae) (Baron et al. 2017) within a creation systematics. When all data were analyzed, three spatially-identifiable groups emerged on PC 1 and PC 2: 1) non-dinosaurs with some dinosaurs, 2) Sauropodomorpha, and 3) a combined (though distinct) Ornithischia/Theropoda association (Fig. 1). For PC 3 nearly all groups were indistinguishable except Ornithischia (Fig. 2). The inclusive Dinosauria plots serve as a contrast to the second culled ordination plot. The second Dinosauria ordinations included Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC 407
