Descripteur : Suborders inside the Archaeocyathida

Type du descripteur : categorical

ARCHAEOCYATHIDA, Okulitch, 1935: Cup two walled, of solitary or low- to high-modular organization, with septal type of development; inner wall of centripetal type; intervallum with taeniae, pseudosepta, pseudotaenial network, dictyonal network, calicles, or syringes; segmented or independent (membrane and plate) tabulae may be present


Loculicyathina

LOCULICYATHINA Zhuravleva, 1955: Cup modular (pseudocolonies formed by interparietal budding) or rarely solitary; intervallum with pseudosepta; synapticulae and plate tabulae may be present.

Anthomorphina

ANTHOMORPHINA Okulitch, 1935: Cup solitary or modular (pseudocolonies formed by external budding); intervallum with pseudosepta and membrane tabulae.

Archaeocyathina

ARCHAEOCYATHINA Okulitch, 1935: Cup solitary or modular (latter by external budding and/or longitudinal subdivision; encrusting forms develop by addition of new central cavities); intervallum with taeniae, pseudosepta, or pseudotaenial or dictyonal network; segmented tabulae may be present.

Dictyofavina

DICTYOFAVINA Debrenne, 1991: Skeleton solitary or modular, latter as branching or massive pseudocolonies (both by intercalicular budding); intervallum with calicles.

Syringocnemina

SYRINGOCNEMINA Okulitch, 1935: Skeleton solitary or modular, latter as branching pseudocolonies (by longitudinal fission); intervallum with syringes.
