A batch of four single Promicroceras ammonites, one also with a fragment of fossil wood.  All nice specimens in a variety of coloured calcites.  A fifth Promicroceras is a double block.  Also a 30mm Microderoceras, damaged on one side but with care can be prepared from the other side.  The final specimen is a juvenile Microderoceras (so fairly smooth), but I think it is a pathological specimen. I suspect a parasitic worm has caused the outer coil to grow in a strange way.  In extreme specimens they can look like the Cretaceous ammonite Scaphites.  An interesting specimen.

All the blocks have the potential for more ammonites.
