Unfortunately, you haven't seen the top view or the right lateral view of
the area in question (the paper describing it is not yet out). There is
signficant damage (including tooth groove marks and regrown bone) to the
neural spines 13-16. More I cannot say until Ken Carpenter has opportunity
to present the information himself: it is a great study.
(However, I think you can see some of these details in CineNova Productions
"Ultimate Guide to T. rex").

If and only if it were a good blow. Nobody says that every strike is
accurate, even for a Tyrannosaurus.
