Potential fossil??

[Rodneymarsh]

Found this rock/fossil on a beach in Northumberland, England. I did not break it open. This is as found. Although dull I believe the reverse side contains Pyrite.

 

Any help in identifying is appreciated

This looks like a concretion. It may or may not have a fossil inside of it.

Thanks Fossildude19. As it's quite "thin" how would be best to crack it open? Any advice of where to make the hammer blow?

I would not hold my breath, however since it looks like two semicircles with a depression running between them I would but a flat chisel into the grove an see if I could tap it open from it there--  dont know if that is the best approach but if there is anything inside it can be prepped from there

Thanks guys.... Just shattered to an oblivion without much being inside! Nothing ventured, nothing gained
