Taxonomy:
Farinacci & Howe catalog pages: Seribiscutum gaultensis *
Morphology remarks: From the original description - "The central area is nearly filled by at least four platelike elements that are interrupted in the center by a pore. The central elements are discernible under the light microscope and form a distinctive extinct
ion pattern"
