Top left: Single Promicroceras ammonite, looks like it extends well into the rock, should be a good large specimen.
Top right: Microderoceras , exposed and slightly damaged on one side. Would prepare better from the other side.
Bottom left: Multiple block of Promicroceras ammonites. Two complete and two partial specimens on the outside of the block, will almost certainly contain more.
Bottom right: Promicroceras ammonites washed among driftwood on the sea floor. A fairly dense layer of ammonites, that consequently will probably be lying in a jumble at odd angles. Several also appear to be hollow, care with preparing! Also contains a larger Xipheroceras . This has a chipped side, which reveals the crystalline interior. Should be a beautiful piece.
