Top: Microderoceras.  Some large calcite veins run around the ammonite but they seem to miss it.  The calcite veins can look attractive and they tell a story.  Ammonite around 35mm diam.

Middle left: A nice multiple block of Promicroceras ammonites, on both sides of the block.  They seem good quality specimens and should make a nice piece.  Seven complete ammonites are visible and a few more partial ones, suggesting possibility of more inside.

Middle right: Another multiple block of nice amber coloured Promicroceras.  Two whole and one partial specimen visible.

Bottom:  Small Microderoceras, again with calcite veins.  About 35mm diam.
