"Megalosaur-like"?  As I recall, only two arm bones are known from
_Megaraptor_: a radius (or possibly ulna?) and one bit of a finger.  (Could
be wrong, though; my only ref is _Nat. Geo._ Dec. '97.)  I believe the idea
was that _Unenlagia_ was the juvenile form and _Megaraptor_ was the adult.
Anyone?
