Triceratops and hadrosaur bones with healed bites from a T rex.  How can
we be sure that a T rex caused these wounds short of having the tooth
still lodged in place?  There is _nothing_ else, not even a Torvosaurus or
something that could have possibly fed on these animals?  I'm just curious
how we know that these are T rex bite marks.  What are their
distinguishing features, or am I getting ahead of myself before a paper is
published on this?
