there is not so pronounced a separation between ornithomimosaurs and other taxa and the “basal” alvarezsauroid Haplocheirus is within the ornithomimosaur cluster (Fig. 29). F. Therizinosauria The BDC results for Clark’s (2004) data matrix, inWeishampel et al . (2004), for the Therizinosauroidea reveals three blocks of positive correlation: two therizinosauroid blocks and a block containing the outgroup (Fig. 30). One therizinosauroid block consists of only therizinosaurids, while the other contains non-therizinosaurid therizinosauroids and the therizinosaurid Nothronychus . There is no shared positive correlation between the two therizinosauroid blocks, and neither block shares any positive correlation with the outgroup taxa. The block containing only therizinosaurids shows extensive negative correlation with the outgroup taxa. Classical MDS results reflect the same separation between Therizinosauroidea and the outgroup taxa, with Nothronychus , Beipiaosaurus , and Alxasaurus midway between the groups (Fig. 31). For PCA, only taxa with about 50% of character data were analyzed. PCA results likewise show a great distance between Therizinosauroidea ( Beipiaosaurus , Alxasaurus , Erlikosaurus , and Segnosaurus ) and the outgroup taxa Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC 412 Figure 4. Biplot of PCA scores (black) and vectors (gray) for Baron’s (2018) data matrix for the Dinosauria. PC 1 accounts for 26.5% of the variance and PC 3 accounts for 15.0% of the variance. Theropods and ornithischians are separated (left, top respectively) with sauropods grouped to the right.
