Abstract
VERY little work has been done on manganese concentrations in shell material and particularly in gastropod shells, although Doring in Vinogradov's book1 reported several analyses and found from 0.1 to 0.0001 per cent manganese by weight in gastropod shells. Krinsley and Bieri2 have determined manganese in the shells of modern and fossil pteropods.
