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.
