Oistoceras , Promicroceras and a gamble!
Top left is a very nice large Promicroceras (25mm +) that looks like it will prepare easily. On the right is a small Oistoceras that would probably benefit from air-abrasive to prepare. It comes from the green ammonite beds to the east of Charmouth. Bottom left is a bit of a mystery! It is a large circular bump in the rock beside a piece of fossil wood. It is probably a large Promicroceras (30mm-ish) that has been drifted against the wood by water currents, but could be something more valuable like an Asteroceras or a Xipheroceras .
Advanced Difficulty (the Oistoceras will require air abrasive for best results)
