<p>(A) PC 1 on horizontal axis, PC 2 on vertical axis. Note proximity of <i>Fa. suarezarum</i> (13) and <i>Fa. utahensis</i> (14), prominent overlap of therizinosaurians, troodontids, and avialans, and minor overlap of tyrannosauroids. (B) PC 1 on horizontal axis, PC 3 on vertical axis. Note shared space of all major coelurosaurian clades and <i>Fa. suarezarum</i> (13) sits adjacent to <i>Fa. utahensis</i> (15), just outside of therizinosaurian, avialan, and troodontid morphospace.
