While I don't have a ref (see previous posts of mine), I have seen some sort of anti-pronation device (if you will), locking the radius and ulna together in a ceratosaur. So, this adaptation probably occured before the ceratosaur-tetanurane split.

What are the anatomical details of this "locking" (anti-pronation) device? Does it involve the distal and proximal ends of the radius and ulna.

Chris
