Carolastraeidae

Eliášová, 1976

Diagnosis

Radial elements are septa stricto sensu, nearly smooth, septal faces, inner and distal edge not (or very few) ornamented, mostly attenuated (not in the glossary !) arranged in radio-bilateral symmetry. A unique major (term not in strict agreement with the glossary) septum = axial septum which characterizes the dorso-ventral plan. The wall was described as an "archeotheca" made of two layers, a lamellar inner layer and a fibrous outer layer. Its transverse section shows external concavities or invaginations corresponding to septa.
