Quite. One of the first things you learn as a scientist designing
experiments is to change only one variable at a time. If you compare
(say) Greg's and Scott's Apatosaurus louisae reconstructions and both
are in the same pose, then you know that the differences you see are
between the two interpretations of the anatomy; whereas if you compare
Greg's Apato with someone else's in a completely different pose, the
the difference you see could be due to the different pose OR the
I think Greg may have missed the point here, and thought we were
arguing for the use of different poses among a single artist's
reconstructions. When we were of course saying the opposite.

Yes -- for example, the gorgeous (if optimistic) galloping Triceratops
on page 224:
and the Stegosaurus ungulatus on page 228:

Well, the Stegosaurus is running, pushing off from its left foot. But
of course lots of the details of the pose are different from what I am
suddenly going to call Paul Normal Form, or PNF for short.
