According to Holtz (J. Paleo., v.68, no. 5, p. 1107), an unambiguous
synapomorphy of maniraptors (sensu Gautier only?) is a long and slender
metacarpal III, yet tyrannosaurs have a very short metacarpal III.
The metacarpal III of Daspletosaurus was much shorter (and much, much
smaller) than metacarpal II: see the photo in D. A. Russell 1970(by the
way--if you ever get to see that specimen, tell me [classroom exercise]
what's wrong with the [incomplete] manus as depicted).
Question: what are the digits in a tyrannosaur manus? Are they I and II
or II and III?
