This is a paleoecological and quantitative investigation of the molluscan faunas of a marl deposit. The purpose of the study is to ascertain what species are present in the deposit, their variation in kind and in numbers with time, and the reasons for the variation, These data yield information useful in reconstructing the development of the lake in which the marl accumulated and in ascertaining the age of the deposit, They permit comparison of the Castalia deposit with other deposits in Ohio and elsewhere and evaluation of the differences and Similarities that exist between them. Investigations of the same kind have been carried out in other pam of Ohio. Similar methods and presentation of results permit close comparison between deposits of different age and from various ecological situations which may eventually yield data for detailed correlations.
