Samples of coal were secured at six inch intervals through two brown coal deposits near Wamsutter, Wyoming. These were macerated and studied microscopically. The coal is of Green River age and contains an abundance of pollens, spores and invertebrate fragments. The plant fossils were studied statistically and stratigraphically and a high degree of correlation between the spectra of the two deposits is evident. Species of the Cycadaceae, Coniferae, Gnetaceae, Myricaceae, Betulaceae, and Tiliaceae have been recognized in the material.
