Classification
Description
Massive ploco-meandroid corallum, generally composed of very short distomodeal or tristimodeal series with lamellar linkage. Rare isolated calices. Radial elements are compact costosepta, free or anastomosed and reaching the columella, straight to curved, bicuneiform, unequal, mostly subconfluent and non confluent. Ornamentation of distal edge, inner edge, lateral faces not known. No pali. Microstructure preserved in traces as a thick, midseptal line. Hexameral symmetry not deciphered, bilateral symmetry marked by the curvature of septa and the lamellar columella. Endotheca subtabular. No synapticulae, wall not developed.
Comparisons
In Brevimeandra costosepta are confluent. Complexastreopsis has no lamellar columella and has montlivaltiid microstructure.
Remarks
Only one species and one specimen described up to now.
