Hi everyone,
Was at a beach in south wales (LLanelli) with family today and tried looking for fossils for the first time and managed to find this. I posted it on reddit and a couple of people suggested it may be preserved cracked mud, but (to my untrained eye!) it seems more regular and clean than ones ive found on google images, and it has those little finger-like projections which dont seem to be on so many google specimens. Some people also suggested a concretion (which I don't totally understand yet, but I'm reading).
Either way I'd really appreciate your input and knowledge. Cant wait to get out there and look for more fossils, I wish I'd started earlier! Thanks for reading
