|---|---|---|
| C. W. Merriam 1974 | These large solitary Papiliophyllinae have curved trochoid and curved ceratoid to subcylin- drical shape. The calice is deep, rather flat bottomed with nearly erect, straight walls and an acute margin without platform. The outer wall has a narrow septal stereozone. The cardinal fossula are well defined, usu- ally on the convex side of the corallum. The major septa of mature individuals number about 60, some of which nearly reach the axis. Minor septa are short. In nepionic and early neanic stages, septa that are thick- ened by the stereome are laterally in contact, and largely filling the interior. In mature stages the septal dilation progressively decreases and becomes confined mostly to cardinal quadrants. Advanced stages have attenuate septa in counter quadrants and those of cardinal quadrants are also thinned, the attenuation is progressively peripherally from the axis. Tabularium is broad, 60-80 percent of mature corallum width; tabu- lae are numerous, normally closely spaced. Some tabu- lae are continuous with the axial sag, others are as wide as the tabellae which are domed and discontinu- ous. The dissepimentarium has one to three columns of large steeply inclined dissepiments, some of which are exceedingly large wall blasts.
Because of the large size and small number of wall blasts and other large peripheral dissepiments, the transverse sections through the mature corallum do not show a conspicuous lonsdaleioid outer zone. The peripheral zone of large dissepiments is well shown only in longitudinal sections. |
