Bivalve oyster shell
Exogyra is the commonest bivalve oyster shell in the lower part of the Upper Greensand, the Foxmould Sands. This is a good specimen and shows the growth lines well. It is from the collection of W.D.Lang, who was a meticulous recorder of information regarding both the fossils and the rocks containing them.
