This would seem to assume a straight fall onto the chest. If a tyrannosaur
slipped while moving
quickly, it may have had enough time to tip itself one way or the other and
slide along on its side.
This would avoid undue forces on the front of the chest, prevent a potentially
and a sliding stop would also help to gradually dissipate the momentum (unlike
a Dirty Harry
style 'sudden impact').
Such an 'inglourious' stop might cause the occasional 'basterd' rib though
(which I believe aren't
that uncommon in tyrannosaur skeletons).
