Deflandrea crassistriata
Deflandrea crassistriata Jain et al., 1975
Now Cerodinium. Originally Deflandrea, subsequently (and now) Cerodinium. See also Ceratiopsis (combination illegitimate).
Holotypus: Jain, Sah and Singh, 1975, pl.6, fig.65
Locus typicus: Assam, India
Stratum typicum: Danian
Original diagnose: Jain, Sah and Singh, 1975, p.8
Shell ovoidal, two layered; periphragm thin, granulate, grana arranged in longitudinal rows forming narrow ridges; forming a broad and tapering apical and two antapical horns. Endophragm moderately thick, ornamented with broad longitudinally thickened strips, each strip followed by a narrow thin, unornamented zone. Capsule rounded to oblong, nearly as big as pericoel, periphragm and endophragm remain in close contact, apically giving a bicavate appearance to cyst. Archaeopyle intercalary, below apical horn.

Cyst width75 µm75-90 µm
Capsule size55x75 µm55-70x75-90 µm
