R. B. J. Benson and X. Xing 2008Tetanuran theropod with the following autapomorphies of the humerus: subrectangular, anteromedially curving deltopectoral crest that protrudes almost as far anteriorly as it is long proximodistally and bears a pitted scar on its anterior surface (modified from Rauhut, 2003), and an obliquely oriented ulnar condyle.
M. T. Carrano et al. 2012Tetanuran theropod with: (1) subrectangular, anteromedially curving humeral deltopectoral crest protruding almost as far anteriorly as it is long proximodistally, and bearing pitted scar on anterior surface (Rauhut 2003; Benson & Xu 2008); and (2) obliquely oriented radial (lateral) condyle of humerus (Benson & Xu 2008).
