Notes: Occurrence is indicated by P = present and + = one specimen per slide. Abundance: A = abundant; C = common; F = few; and R = rare. Preservation: G = good. B. invaginata = Buccinosphaera invaginata; C. tuberosa = Collosphaera tuberosa; A. angelinum = Axoprunum angelinum; A. ypsilon = Amphirhopalum ypsilon.
