  It would me. *Deinocheirus* has all three metacarpals of
subequal length, I-II compressed together for over three
quarters of their length, II-III compressed completely,
elongated phalanges with inturned flexion so the fingers flex
towards each other, flattened to oblate carpals, a slender
humerus with no epicondylar crests, a small deltopectoral crest
restricted to the proximal 1/5 of the humerus, small and
triangular, little medial inflection of the head, all of which
are synapomorphies of Ornithomimosauria, including
*Pelecanimimus,* *Anserimimus,* and classic ornithomimids like
*Gallimimus* and *Dromeciomimus* and *Archaeornithomimus.*
