separated by gaps in morphological space; however, Buitreraptor does fall in between the troodontid and dromaeosaurid clusters (Fig. 59B). We determined to include the scansoriopterygids in the oviraptorosaur analysis since there was shared positive correlation between them and the oviraptorosaurs in the main analysis. Additionally, scansoriopterygids are often near oviraptorosaurs in phylogenies, as is the therizinosauroid Falcarius , which we also included as an outgroup. The BDC results (Fig. 60) for this analysis (89 characters, 14 taxa, 0.35 TRC (to include more oviraptorosaur taxa)) show twomajor blocks of positive correlation: Scansoriopterygidae and Oviraptorosauria. The scansoriopterygids share negative correlation with the oviraptorosaur block of taxa and with Caudipteryx , which does not correlate with any other taxa. Falcarius and Protarchaeopteryx also do not correlate with any other taxa in the analysis. The caenagnathid oviraptorosaur Chirostenotes correlates positively with Citipati in the oviraptorosaur block, but not with any other taxa in the analysis. The “basal” oviraptorosaur Avimimus only correlates positively with Oviraptor and negatively with Epidendrosaurus . The 3D MDS results (Fig. 61) show the two scansoriopterygid taxa clustered together and both far away from any other taxa in the analysis. The remaining clustering is difficult to interpret. There is definitely a tight cluster of oviraptorosaurs that corresponds to the oviraptorosaur block in the BDC. The closest taxa to this cluster are Oviraptor , Caudipteryx , and Chirostenotes . Avimimus is farther away than expected from the BDC results. Falcarius and Protarchaeopteryx are both far away from the main cluster, but somewhat close to Caudipteryx and Chirostenotes . The subset analysis for the rest of the taxa (137 characters, 21 taxa) was analyzed at a 0.4 TRC like the total van der Reest and Currie (2017) analysis. The BDC results (Fig. 62) show three blocks of positive correlation: 1) Alvarezsauridae, 2) Ornithomimosauria, and 3) the rest of the taxa except Erlikosaurus , which does not correlate positively with any other taxa in the analysis. The two alvarezsaurids do not correlate positively with any other taxa in the analysis, and they correlate negatively with Archaeornithomimus and with many taxa in the large, non-maniraptoriform block. Several ornithomimosaur taxa correlate negatively with Allosaurus and Sinraptor , and Pelecanimimus and Ornithomimus correlate negatively with Dilong . Harpymimus is the only ornithomimosaur to correlate positively with the large block. The MDS results (Fig. 63) show Erlikosaurus far away from all other taxa, and the two alvarezsaurids are close to each other, but separated from the other taxa by a large gap in morphological space. The remaining taxa fall into three separate clusters that make a line in morphological space, except for Archaeornithomimus , Tanycolagreus , and Falcarius , which do not fall into any of the three clusters. The cluster on one end contains the tyrannosauroids and the non-coelurosaurs. The cluster in the middle contains the “basal” coelurosaur taxa. The cluster on the other end contains the ornithomimosaurs, except for Harpymimus , which is positioned halfway between the ornithomimosaur cluster and the “basal” coelurosaur cluster. 5. Lamanna et al. (2014) Results The BDC results (Fig. 64) for the oviraptorosaur matrix used by Lamanna et al. (2014) shows three main blocks of positive correlation. One block, containing the outgroup taxa, correlates negatively with the large oviraptorosaur block of positive correlation. The outgroup taxon Velociraptor also correlates negatively with the caenagnathid oviraptorosaur Anzu , which does not correlate with any other taxa in the analysis (although when run at a 0.3 TRC, Anzu positively correlates with Gigantoraptor , which positively correlates with Conchoraptor in the oviraptorosaur block (see Appendix, Fig. 74)). Avimimus also does not correlate with any other taxa in the analysis. The final block of positive correlation contains two “basal” oviraptorosaurs: Incisivosaurus and Caudipteryx . The 3D MDS results (Fig. 65) show three clear clusters of taxa, separated from each other by large gaps in morphological space. Anzu is not close to any of the clusters. The larger cluster contains the oviraptorids, and then there are two clusters of three taxa each: 1) the outgroup and 2) Avimimus + Caudipteryx + Incisivosaurus .
