Hi can anyone tell me what made the lovely pattern on this stone? Not sure if it’s fossil or just from some old plant life.

Hi Louise,
had the very same thing myself a while ago and someone on-line suggested marks left by a worm type creature...something beginning with T. They still around today and do that to rocks and shells so not a fossil at all. Yours may be different as it has some 'form' to the rock.

High Louise, yes that's about it I'm afraid, but keep your eyes peeled!

Are you thinking of Toredo Bobo?

I’ve looked up the teredo Navalis shipworm but only says about wood. Do these guys eat rock too?!? Also they are fine surface imprints rather than any deep boring.

Think that was it...that was what someone on here said it was anyway.
Can't find the old post-must have been before the software upgrade

My other rock with colourful layers and variable depth borings looks to me to be made by teredo or piddocks. But I still can’t see how my original one is like that. Any more inisight prep01?

You get the burrowing then of course you get weathering. I had a few pieces just like it with varying degrees of weathering....I originally thought I had found some kind of fossil sponge but when I looked on-line definitely the old worm playing tricks

Louise, it now matters exactly where each was found to answer your question.

First one at blackheath, near Guildford surrey, found at the edge of a puddle but miles from the sea (feels like chalk stone, similar to the echinochorys cast I’ve got hence my immediate interest). The second one with the layers found on the railway track in rudgwick. West Sussex but as it’s a man made track so could have originated anywhere

The second one looks like flint to me.
Best wishes from the Lake of Constance. Roger.

Hi Louise, The first one as you say may have come from anywhere but may be from the Greensand formation and are sections of burrows made by ?Piddock bivalves, then eroded. The second one could be flint but looks more like Chert but are the same type of crystalline Silica (SiO2) and may have come from the Wealden deposits around that area.
Hope this answers your question.
