So it's a colonial coral, not the most common that we have, which is why it's interesting to see it like that.

Just reminding you that these rocks are originally marine sediments deposited in shallow tropical waters.

Yes.

How long ago?

350 million years ago, roughly, in the Carboniferous era, when Ireland was essentially around the equator.

Pangea.

Just before the formation of Pangaea, there was still a bit coming in, being added on a bit later, yes.

Yeah, but it existed at the bottom of the sea and eventually died and was mixed up with the sediment that became this rock, yes.

I don't think it does change it that much.

I mean, you could switch the number and it would still be impressive.

You know, for most people on an everyday basis, you'd just be... 100 million, 150 million.

It's older than the dinosaurs and all of that.

Yes, it does.

And it's an abstraction.

I personally believe no human beings can ever comprehend that.

We're just not made for that.

However, the human species and others at the surface, that's a different story.

that's a more universal response in the sense that they shape activity and culture everywhere the bedrock influences the soil here we're in limestone bedrock a few kilometers west we switch to much older rocks that are

either other types of sedimentary rock sandstone conglomerates or metamorphic rock quartzite schist and a bit further down marble in turn especially when it comes to agriculture you know it doesn't allow you to produce the same thing or as easily anyway

They would have to do a lot of work on the field, like in that film we talked about, the field before.
