But then you can start piecing some other stuff together.

So in this case, the skeleton is pristine.

It's one of the best hadrosaur skeletons out there.

It's certainly the best from Mongolia I've ever seen.

And all the bite marks from one bone, the humerus, the upper arm bone, every mark.

We went over the rest of the skeleton, nothing.

And then the humerus is chewed to bits.

There's bites all over it.

But when you look, there's two really distinctive patterns.

There's deep circular punctures.

And remember what the shape of this thing looks like.

Yeah.

At the ends.

And then along the delta pectoral crest, okay, it's much, much bigger than a hadrosaur, but this bit, remember that's where all the big muscles attach.

There's all of these types of, this is from a different bone, but different animal, but all these types of close parallel scratches.

And so that looks like selective feeding because it's using its giant crunchy teeth at the ends to get the bone off.

And this is off a buried skeleton.

And then it's got these... Actually, T-Rex has really small teeth at the front of its mouth.

Right in the front where our incisors are.

They're called incisiform teeth.
