Palynology of the Almond Formation (Upper Cretaceous), Rock Springs uplift, Wyoming

The palynomorph content of the Almond Formation (Upper Campanian) was investigated using 80 samples from six measured sections on the east flank of the Rock Springs Uplift, Wyoming. A composite standard referenec section of the total Almond and four additional sections of the marine interval of the upper Almond were used. One hundred thirteen species of palynomorphs were identified. Five new species are described. The affinities or possible relationships of the form species with living plants are noted. Paleoenvironmental and paleoecological investigations were made using the distributions and stratigraphic range of the species; the absolute abundnace of species, groups of species, and dispersed plant tissues; the ratio of marine species to nonmarine species; the diversity of the palynomorphs and the cluster analysis groupings of species. The marine upper Almond Formation is easily distinguished by the presence of 25 species, mainly dinoflagellates and acritarchs, which are restricted to it in the sections studied. The dinoflagellate species, Trithyrodinium druggii Stone, n. sp., is abundant and restricted to the marine upper Almond and may be used to characterize it. The dinoflagellate species, Deflandrea cooksoni Alberti, has a restricted range within the upper Almond and is used to subdivide the marine interval.
