Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC 425 Figure 40. PCA scores for Foth and Rauhut’s (2017) data matrix for maniraptorans with the most complete data. PC 1 accounts for 34.2% of the variance and PC 2 accounts for 17.6% of the variance. The more complete dataset reveals a bifurcation with two morphoseries. Dromaeosaurids, at the base of the bifurcation, ordinate separately from avialans for PC 2. Avialans connect two morphoseries. Numbered groups: 1) “basal” coelurosaurs; 2a) dromaeosaurids; 2b) “basal” avialans; 2c) troodontids; 2d) alvarezsaurids; 3) ornithomimids; 4) oviraptorosaurs; 5) ornithuromorphs; and 6) avians + Lithornis . Numbers provide relative order of first appearance in fossil record with initial members of the second group appearing nearly simultaneously. Figure 41. PCA scores for Foth and Rauhut’s (2017) complete data matrix for maniraptorans with the most complete data. PC 1 accounts for 34.2% of the variance and PC 3 accounts for 14.5% of the variance. PC 1 and PC 3 reveals a similar morphospatial bifurcation though with overlap between dromaeosaurids, avialans, and oviraptorosaurs at the base of two morphoseries. Figure 42 . BDC results for Galton and Upchurch’s (2004a) data matrix of “Prosauropoda”, as calculated by BDISTMDS (relevance cutoff 0.8). Closed squares indicate significant, positive BDC; open circles indicate significant, negative BDC.
