There's some cactuses and things which maybe do something a little bit similar.
But the cladoxylopsids are really fairly unique because the way that they support themselves is with this very much divided woody structure around a hollow interior.
It's a bit like the Eiffel Tower inside the plant, holding it up.
And then with these monkey arm branches on the side of them, which are then dropping off as the apex grows upwards.
It's a form that we might recognise from a palm.
I'm sure Bill might talk about this.
or a tree fern, but without actually having any leaves.
So a quite unusual type of structure, but quite distinctive.
This will not be till probably about 200, 250 million years later.
So these early Devonian forests are really quite distinct.
And one thing you should perhaps recognise is there's no seeds there.
There's no flowers.
There's almost no insects, maybe just millipedes.
No birds.
Very low diversity.
Not this tropical ecosystem that we think of today as being a tropical forest.
This is really something very distinctive.
And without the level of interactions that Jenny's talked about earlier,
perhaps apart from the fungi in the soil, which might be quite interesting.
One of the interesting things about how trees grow is where the growth occurs, where the primary growth occurs.
