#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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?

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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

Nowadays, again, tech's getting better.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

You just got a 3D model in the computer.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

Yeah, but where you found everything.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

It absolutely got moved.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

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

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

Well, maybe it's from something else.
