Ammonite

This ammonite fragment is important because Caenisites turneri is one of the zonal ammonites for the part of the Lower Lias called Shales-with-Beef. Zonal ammonites can be used to match up layers of sediment found in widely separated areas. Even a small piece of ammonite like this, if identifiable, can be used in this way.
