Abstract
A new genus of Late Triassic palynomorph, Froelichsporites, is created and designated here for azonate, obligate tetrahedral spore tetrads which characteristically are found in Upper Triassic continental (fluvial, interfluvial, and lacustrine) strata of the Newark Supergroup of the eastern United States and Canada, the Dockum Group of Texas and New Mexico, and the Chinle Formation of New Mexico, Arizona, and Utah. This palynomorph is restricted geologically to strata comprising the upper Carnian and Norian Stages of the Upper Triassic, and is a geographically widespread form. This monotypic palynomorph, Froelichsporites traversei (Dunay & Fisher) comb. nov. et emend., is most abundant in the conterminous U.S., but it also has been found in portions of eastern Canada and possibly may be present in Upper Triassic strata of Portugal.
