While I don't know about that, *Coelophysis* was apparently still able to
rotate its lower arms, while *Allosaurus* (pers. obs. on the cast in the
museum here) and more birdlike theropods can't do that

But what specific features did you "personally observe" that led you to this conclusion - that tetanurine forearms are less rotatable (i.e. supination/pronation) compared to coelophysids?

Thanks in advance.
