Right.

And so this is very peculiar.

And Fonky do tubes.

We know they're made of filaments called mycelium, but not in that fashion and not that big.

We don't have eight meter mushrooms today.

Yeah, so in that case, we have some specimens that are preserved in exceptional conditions.

So the work we've been carrying on with my team in Edinburgh before coming here was looking at some of those exceptional preserved specimens from a deposit called the Rennie Chert in what is today Aberdeenshire from the town of Rennie.

But at the time, you imagine this was a wetland in a tropical area.

And all of the organisms from that environment have been preserved frozen in time in rock, siliceous rock.

And thanks to that, we have the 3D organisms preserved and we can really, really see the internal organization of them.

So we see those tubes, we see how they branch and how they orient themselves in space.

We have something in three dimension.

in opposition to some fossils that can be preserved as flattened with no internal morphology.

So that's those very, very rare, but also very, very important fossils that allowed us to learn more about how those things were.

Yeah, so the really odd thing is that everybody agreed that this was closer to a fungus than anything else.

But even if it was a fungus, this was still odd.

There's so many things that was not working.

Like what?

So, for example, we...

We don't know exactly what they would have feed, what they would have eat.
