Callocystitidae

Pseudocrinites magnificus, from here.


Belongs within: Glyptocystitida.

The Callocystitidae are a group of Upper Ordovician to Upper Devonian cystoids distinguished from related groups by their particularly long ambulacra.

Characters (from Kesling 1967): Rhombiferan cystoids provided with distinct pectinirhombs; periproct relatively small, not produced; theca ovate, globular, biconvex, or ellipsoidal, not spindle-shaped or resembling a pentremite; rhombs relatively few, rarely developed as demirhombs; ambulacra long, extending down over theca; column present.
