And they took like 20, 30 feet off the top of a hill to get down to this fossil.

You know, so something, you know, probably half an acre in size, 20, 30 feet of rock.

What's with the plotting and the diagramming?

You may well have seen something like this for archaeology shows or something like that.

Nowadays, again, tech's getting better.

People are using drones and stuff for this or taking hundreds of photos and then building photogrammetry models.

You just got a 3D model in the computer.

Or just kind of modeling what we're looking at here.

Yeah, but where you found everything.

So it goes back to that stuff we were saying about the process of fossilization or the process of what's happened to that animal from death to discovery is, okay, a classic thing is bones being in a line.

So you can imagine if, you know, bones are lots of weird shapes, but mostly, or certainly lots of bones, ribs, arms and legs, things like this, they're quite long bones.

So if they're in a current, they will tend to spin in the axis so that they are facing the current.

So if you're finding all the bones are in a line,

That probably tells you that this thing has had quite a lot of water washing over it.

You're then probably going to be missing most of the small bones because the big heavy bones won't be shifted by that current, but maybe the small ones will.

So it might tell you where to go and dig further down the hill, quite literally, but it can also just tell you, okay, this thing, there's no way this thing died here.

It absolutely got moved.

So we need to factor that in when we're trying to interpret it.

Or we've got this one weird bone and we can't work out what on earth it is.

Well, maybe it's from something else.
