Gleviceras is one of the more unusual ammonites preserved in iron pyrites. It is found simply lying on the beach, especially after rough weather.
This one was found by Barney Hansford who lived in Charmouth. Between the 1950s and the 1970s, he built up a large collection of local fossils and displayed them in Barney’s Fossil Exhibition in Charmouth. After his death in the late 1980s, the collection was broken up, but some specimens found their way to Bridport Museum’s collection.
