Aquilapollenites (Rouse) Funkhouser — Selected Rocky Mountain taxa and their stratigraphic ranges
The genus Aquilapollenites and its type species, A. quadrilobus, are redescribed, and the latter is illustrated. This report summarizes our present information on stratigraphic ranges of selected Rocky Mountain species and varieties of Aquilapollenites. Of the 17 taxa included in this report, 10 are previously named species, 4 are new species, and 3 are new varieties. One species is transferred from the genus Mancicorpus and another from the genus Parviprojectus. The stratigraphic data concerning Aquilapollenites incorporate available information from U.S. Geological Survey pollen collections.

Aquilapollenites: Fossil pollen as seen under the scanning electron microscope
Photographs of a Late Cretaceous species of Aquilapollenites illustrate the usefulness of the scanning electron microscope (SEM) for the study of fossil pollen . The SEM has the advantages of great depth of focus and wide range of magnification; using present techniques, its use for the study of unsectioned specimens is limited to the observation of surface detail.

Plant and miscellaneous microfossils of the Pierre Shale
This preliminary report summarizes part of a Survey program to study, in detail, the stratigraphy and paleontology of a nearly complete sequence of Pierre Shale near Redbird, Wyoming. The physical stratigraphy and correlations are being analyzed by James Gill and W. A. Cobban. Various groups of invertebrate fossils are under study by Mr. Cobban, N. F. Sohl, and James Mello. Plant microfossils are the responsibility of Estella Leopold, assisted by Bernadine Tschudy.
