This is strange research. What about very minute movements of the
head, neck arms and trunk, not to mention some help from the tail that
could help an allosaur with a turn. It would be interesting to see how
much the trunk and tail could aid in a turn. I cerntainly don't think
that the rest of their anatomy was a stiff as a board, literally.
