Ceratiopsis speciosa ssp. speciosa
Ceratiopsis speciosum spp. speciosum
Autonym
Now Cerodinium speciosa ssp. speciosa. Originally Deflandrea speciosa ssp. speciosa, subsequently Ceratiopsis speciosa ssp. speciosa (combination illegitimate), thirdly (and now) Cerodinium speciosa ssp. speciosa.
Holotype: Alberti, 1959, p.97, pl.9, fig.12-13
Locus typicus: Mecklenburg, Germany
Stratum typicum: Upper Paleocene

Original description as Cerodinium speciosum: [Alberti 1959, p. 97]: (Translation: LPP):
Description:
Shell flattened, outline elongate pentagonal. With a distally narrowing short apical horn, and two strongly diverging, tapering antapical horns. Transversal furrow slightly deepened, longitudinal furrow sometimes indicated on the hypotheca. On the periphragm denticulated ridges, which could belong to the tabulation. The capsule often positioned close to the shell. Shell membrane and capsule ornamented with small, distinct closely arranged tubercles, which also could be absent on several positions.
Additions: The species is characterised by the strong diverging of the widely separated antapical horns. A tabulation could not be recognised. A rounded-trapezium shaped archeopyle is located below the apex. The membrane of the shell is transparent; the membrane of the capsule brownish.
