Description
Apparently meandroid flabelloid but it is probably the base of a phacelo-meandroid colony. Outer surface covered with equal costae. Intracalicinal increase producing short series. Radial elements compact or subcompact (?), curved. Distal and inner edge not observed. Lateral faces with pennulae. No palis. Microstructure unknown. Hexameral symmetry not deciphered, bilateral symmetry marked by the curvature of septa. Endotheca of vesicular dissepiments sloping down to the center. Probably a parietal columella. Synapticulae not observed but possibly present. Wall absent within a series but present close to the periphery of the colony.
