Do you know of any refs that support this point (I'd like to see them).
So far, the "it's misarticulated" argument has been floating around in sever=
topics; this is simply too easy a way to discredit the points of the reaserc=
especially since there is often little data to prove it.
Contrary to populat opinion, there is osteological evidence to suggest that =
sprawling forlimb is correct. Look at the shoulder joint of _Triceratops_. =
the upper humerus, there is a triangular shaped process. This matches exact=
with an identical process on the scapulacorocoid. Since these features=
match up, it would suggest that this is the correct placement. We would=
expect this deductively: if a large animal was to have a sprawling limb,=
immense stresses would build at the shoulder joint. Therefore, we would=
expect to see a reinforcement of the joint (as this feature shows). Since=
we do see it, this is another piece of evidence to support the idea of a=
