When crocs thrash their heads sideways at each other, they can do a lot
of damage with their protruding teeth. If tyrannosaur teeth hung out to
any degree (and I think it is clear they did, although not curved
laterally like those of crocs), they may have done superficial damage
with a badly-timed headbutt.

I also think it is important that tyrannosaurs show HEALED bite marks.
If a T.rex bit another animal on the head with all of its force, I doubt
the wounds would have had a chance to heal. :)<<

Hmmm...Didn't think of that, in fact that might help explain why some of the
marks are from a single tooth and not from a whole jaw. Interesting...

An apology? Okay... what have you done with the REAL Tracy Ford?<<

What was that saying in the latest Mike Douglas movie? Oh yea, I'll
neevvveeerr tell :)


My original comment was intended as tongue-in-cheek (hence the smiley
face after it). I'm sure no-one thinks of you as
quick-tempered.........?<<

Smilely face, let me see.

Of course, everything I just said about dinosaurs is pure speculation,
so it's certainly nothing to get worked up about (not that HP Ford did -
THIS TIME - but based on past experience, I know how passionate he can
get about his beloved archosaurs).  :) <- There it is, sorry missed it the
first time. :(

Do the T. rex's that show teeth marks to the head show damage corresponding
to teeth in both the upper and lower jaws of an attacker (as if the attacker
took the head or snout in its mouth and bit down), or are the teeth marks
isolated (such as might be caused by head butting or some kind of stabbing
or thrusting behavior)? Seems like the evidence should provide some insight
into such things...<<

I'm not sure, I just know they have tooth marks. Something for someone to
look into, that's for sure. I'll have to ask Darren Tanke, he's the one who
has done research on it.
