Promicroceras, Microderoceras, Cymbites & Caenisites Nodule (Popcorn Stone)
A fantastic multi-ammonite block. It contains Promicroceras, Microderoceras, Cymbites & Caenisites ammonites. This type of nodule is sometimes known as a 'Popcorn nodule' as the ammonites appear on the surface. These blocks aren't very common and can only be found on extreme low tides which occur at most once a year. They are also extremely tricky to prepare and only a few people have the skill and equipment to prepare them.
