About a year ago now I picked up a chunk of boulder with a nice chlamys and other bits and pieces in it from the boulder field west of eype mouth near thorncombe beacon.
At the time I found some odd markings on the weathered outer face of the fragment but promptly forgot about it until I spotted it again the other day.
Its a section through something but I'm not sure what - there appear to be two 'limbs' and a central 'body' part plus a number of dis-articulated fragments.
Is it a section through a lobster? Its pretty small - the 'limb' in the first photo is only 25mm long.
