Hi suf, I think it's a devils toenail but its shell is being converted to beekite. The carbonate shell is being replaced by concentric rings of microcrystalline silica (chalcedony)....A very nice example....

Wow that's exciting! Thank you Pete!
I spent some time on the web searching for similar looking objects and did not see anything like it, including devils toenails!
Yes, it doesn't show up on
here very often but it's pretty obvious when you see it, had to scratch
my head to remember the name of the damn stuff. Here's a Jurassic oyster
I came across on the Glamorgan coast....very similar pattern to
yours....

Fine examples of beekite replacement, both of you - I haven't seen it on Gryphaea before. 🙂

Amazing! and fascinating! I've been down another rabbit hole on the internet all about Chalcedonized fossils!

more question: We rinsed a bit of mud off the fossil after we found it,
but i was reluctant to give it a proper scrub as it seems like it might
be fragile, so I'm wondering what's the best way to clean it?
I wondered if the broken section was cracked in prehistoric times or more recently
