Eocaudina

Aggregation of sclerites of Eocaudina septaforaminalis, from Boczarowski (2001). Scale bar = 200 µm.

Belongs within: Calclamnidae.

Eocaudina was originally established as a genus for sieve plates known from the Ordovician to the Pleistocene (Boczarowski 2001; Frizzell & Exline 1966); more or less complete scleritomes have since been discovered (Boczarowski 2001).

Characters (from Frizzell & Exline 1966): Sieve plates, circular to hexagonal or irregular, not multilayered.
