Abstract


Three distinctive new genera of acritarchs, microplankton of probable algal origin, are described from the Early Devonian (Late Gedinnian) Haragan Formation of Oklahoma. Ozotobrachion includes two new species: O. dactylos (type species) and O. dicros. Fimbriaglomerella (type species, F. divisa) and Riculasphaera (type species, R. fissa) are both, for the present, monotypic.
