The value of the organic cement matrix in the identification of the shells of fossil testate amoebae

Colin G. Ogden and Robert L. Ellison

Abstract. Shells of fossil testate amoebae isolated from lake sediments in England and Canada have organic cement matrices similar to those possessed by Recent specimens. The surface patterns of individual building units can be useful taxonomic features for confirming the identification of the many species of Difflugiidae found in these environments.
