And again, that's what they were doing 150, 200 years ago.

That hasn't changed.

Where it gets more complicated is if you've got really hard rock that's very hard to get through, particularly if the bone is fragile.

Then it becomes difficult because if you want to get a jackhammer in, the vibrations means you're going to shatter your bones before you've even cut through the rock.

So then you might be down to doing it manually.

Yeah.

And then it was like... Yep.

Hand chipping it out.

Yeah.

The other way you end up with that is...

Like the classic Jurassic Park thing, like the second scene and they're digging in the desert and there's the whole skeleton laid out and five or six guys all digging around it and exposing it.

And that's actually quite common in the States.

And the reason is huge amounts of those excavations are being done on government land, their national parks or whatever, or protected land.

And very often the rules are you're not allowed wheeled vehicles.

full stop at all to protect the environment.

You can walk in and walk out, but you can't drive.

And it's like, well, right.

When we're in the desert in Mongolia, in China or China or Mongolia, and we're allowed to do this literally.

Yeah.
