Introduction

This catalog, which is up to date as of 1964, is presented as a supplement to the Paleozoic content of A. C. Peale’s paleobotanical catalog in United States National Museum Bulletin 53, part 2, section 3, published in 1907 as “Catalogue of the Type and Figured Specimens of Fossils, Minerals, Rocks, and Ores in the Department of Geology, United States National Museum: Part 2. Fossil Vertebrates; Fossil Plants; Minerals, Rocks, and Ores.” It was prepared under the direction of George P. Merrill, then Head Curator of Geology.

Genera are listed alphabetically, as are the species under each genus. An index to species is provided for convenient cross reference. The age used for each specimen is that of the referenced author and does not necessarily reflect present U.S. Geological Survey usage. The numbers following geologic age in each entry refer to numbers in the United States National Museum paleobotanical catalogs. The abbreviated references indicated in each entry are cited fully in the bibliography.

A very small percentage of the specimens listed here have not actually been illustrated, but inasmuch as they were textually isolated or represent unfigured parts of figured specimens they are included. Furthermore, typological status of specimens is not indicated here because in so many cases it is obscure; this is particularly true of material treated in the older works, in which types were not designated.
