OK, so I pace fields near to Axmouth and Lyme Regis.
Am finding fossils regularly, and although I think I may know what they might be, I could do with some help regarding how old, and maybe also how a Chert Nodule is even formed.
Pictures attached. They're all peachy, in my opinion. I can enlarge any of these, if required.
Micraster Urchin(s), Echinorys Urchin, Mussel(s), Oyster, Seashell, Coral, Scallop Sp. and a fragment that looks like is should be something.
