Does the ulna bear a well-developed olecranon process?  This is referred
material, so it may not have much bearing on the affinities of the holotype.
(You know how it goes with those Continental Intercalaire fossils...)

An obvious question, and I don't mean to sound facetious: if the middle
portion is missing, how do you know how long/short the humerus is?

_E. gautieri_ an alvarezsaur?  Very intriguing...
