That is.

You find these things...

And I say, obviously, I've been finding probably must have found somewhere in the region about 50,000 fossils now.

That's probably what I found over my career.

And you still have like that magical kind of experience seeing that because also you never know.

You could have popped that open.

There could have been a tooth in there or something.

You don't know.

Yeah, that sort of thing.

So if you imagine it as kind of like, a bit like a snail inside a hardened shell and think of like an octopus and the octopus would have been

So it's a curled shell and then kind of the opening that have been kind of all arms and like you've seen.

Yeah, like Omanyi, Omastar from Pokemon, that sort of thing.

So it is, but what's happened, so that animal's died and then the original structure of that shell has been replaced by sediment.

So imagine this animal's died.

You could use a Pokemon.

So imagine Omanyte's died, gone to the, which is very sad, gone to the bottom of the seabed.

It's been covered over by sand and sediment.

And then over time, over millions of years, the original structure is replaced by minerals from the surrounding sediment.

And that's what causes fossilization.

That's a process called permineralization.
