Type invertebrate fossils of North America

This catalog is prepared in a manner similar to the "Catalog of North American Devonian Fossils" published by the Wagner Free Institute of Science in Philadelphia. The Early Tertiary catalog will contain descriptions and illustrations of the fossil invertebrates from the Paleocene, Eocene, and Oligocene of the Atlantic and Gulf Coastal Plain of the United States. Each species will be described and illustrated on a card of heavy paper 8 by 11 inches in size, fitting a letter file. The text of the cards will be printed; the figures will be printed by full-tone collotype process. Type specimens will be figured if available; if not, photographs of topotypes will be used wherever feasible. Photographs of topotypes will be used extensively as supplementary illustrations. Original descriptions will be quoted in every case. Additional remarks or complete redescriptions will be given where necessary. Type localities and stratigraphic data have been checked in the field by specialists in nearly all cases and will be given explicitly and in an up-to-date manner. Therefore, the cards will contain much more information than is available in the literature today.
