... sponge fossil. Sponges around UK much more common than people realise.
Can we tell from this photo that this is a fossil? Perhaps it could be a dead sponge? Valerie, did you note whether the specimen was hard or soft, heavy or light?
I still have it, it is very light weighing just 24g and measures approx 6x6x8cm.

Not likely to be a fossil then, but a dried sponge of some sort. Or perhaps a soft coral, such as Alcyonium digitatum Dead Man's Fingers. Probably not possible to tell from an old specimen like this.
... I agree - old specimen - do not think coral - doesn't look like dead man's fingers as I have seen old specimens of this. Would still go old sponge due to the pores. I have some contacts that may recognise more than I can and I will ask. Keep you informed.
