Deflandrea speciosa ssp. speciosa
Deflandrea speciosa ssp. speciosa
Autonym
Now Cerodinium speciosum ssp. speciosum. Originally Deflandrea speciosa ssp. speciosa, subsequently (and now) Cerodinium speciosum ssp. speciosum. See also Ceratiopsis speciosa ssp. speciosa (combination illegitimate).
Holotype: Alberti, 1959, p.97, pl.9, fig.12-13
Locus typicus: Mecklenburg, Germany
Stratum typicum: Late Paleocene
Translation Alberti, 1959: LPP
Original description: Alberti 1959, p. 97
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.
