[ Prasapora ]

Prasopora Nich.-E., 1877 [*P. grayae] [=Prasoporella Vinassa, 1920]
Free discoid to hemispherical masses. Zooecia lined by overlapping cystiphragms connected by diaphragms.
Ord.
Order Trepostomata Ulrich, 1882
Free walled stenolaemates of typically robust colonies with maculae. Colonies mostly dendroid, others encrusting or massive, few frondose. Feeding zooids budded throughout endozones in almost all taxa. Most feeding zooids long with basal diaphragms; positioned adjacent to each other without apparent pattern and with only one type of aligned style intervening; apertures closely spaced. Body cavities of feeding zooids in exozones generally equidimensional in cross section, either circular or polygonal. Most zooidal skeletons laminated in exozones, laminae parallel to growth surfaces. Many with small polymorphs between maculae, with or without diaphragms.
E. Ord. - Triassic
