And you can pull the little tooth out.

And then there's a T-Rex foot bone.

with these distinctive feeding traces on them.

And this actually goes back to that early point about T-Rex being weird, being the only big carnivore it's an environment.

Because if this was even Mongolia at that time, but anywhere else, there's three or four or five big carnivores.

And so you find a bone and it's chewed up by a big carnivore.

We don't know who did it.

But when you see a big bone chewed up in a T-Rex ecosystem, well, you know, if it's anything bigger than this, you know, it was T-Rex.

And so when it's a T-Rex bone with T-Rex bite marks.

Yep.

QED.

Yeah.

So it must have been.

That's fascinating, isn't it?

That they would attack themselves.

Cannibalism turns up in a whole bunch of stuff, right?

but it's very rare as like a fairly habitual behavior.

Yeah.

It could, but it's unlikely.

And in this case, so again, we see there are loads of facial injuries in tyrannosaurs, in carnivorous dinosaurs generally, but particularly tyrannosaurs.
