...... it doesn't explain the mechanism of its appearance, which I am eager to know...This is a guess, but it looks as though the soft clay has been lying on a bed of pebbles.

I was walking in the fields here in Cambridgeshire the other day and picked up this interesting piece. I'm wondering if anyone can explain to me how this pattern forms?

unless of course its soft clay thats been laying on a bed of pebbles and not a fossilized piece of rock.
PS - I think @Bass you trump the @Colin2B gravel in clay hypothesis!Trump? Trump?
It looks like hexagons to me, straight lines, most efficient construction method I believeYes, but it also occurs incidentally whenever items are packed together eg honeycomb.
It could be made by the same process that produce d the giants causeway, maybe even by the same giant.It looks like hexagons to me, straight lines, most efficient construction method I believeYes, but it also occurs incidentally whenever items are packed together eg honeycomb.

Trump? Trump?There are much ruder words for a fart.
How dare you use that foul word sir?

A Trump might be a fart in England, but a Johnson is something you pee with in America. :)Trump? Trump?There are much ruder words for a fart.

Not clear from your photo, but do you have any of the central raised pips?
Yes, I think, with the eye of faith, at least one is vaguely discernible: look at the facet above 3 on the ruler in my image - there are markings there that correspond to the central regions in the Moroccan specimen.Yes, that’s what I was looking at. Are there any in the other indentations?
I had been thinking along the lines of pipe rock, but with hindsight it is a piece of coral, as mentioned above.I agree, in pipe rock the burrows tend to be well spaced like ragworm on the beach.
We shall overcomb!;D ;D
Hard rock suggests limestone- I still vote for coral!Yes, I was wondering if you know what we are looking at in the Moroccan coral. Are these originally hexagonal creatures or is this an artefact of the fossilisation process? I’m intrigued by the white boundaries.
Trumped? We shall overcomb!What's your view on a drop of vinegar?

indicating the structure goes right through the rock. Any sign of that on your specimen?
