Rhynchodiniopsis regalis
Rhynchodiniopsis? regalis (Gocht, 1970) Jan du Chene et al., 1985
Originally Leptodinium, subsequently Hystrichogonyaulax, thirdly (and now) Rhynchodiniopsis?. Jan du Chene et al., 1985 considered this to be a "provisionally accepted species" of Rhynchodiniopsis.
Holotype: Gocht, 1970, pl.33, fig.6, text-fig.10; Jan du Chene et al., 1986, pl.98, figs.6-10
Age: Early Bathonian
--------------------------------------------------
G.L. Williams short notes on species, Mesozoic-Cenozoic dinocyst course, Urbino, Italy, May 17-22, 1999 - LPP Rhynchodiniopsis regalis has a rounded to polygonal outline. The epicyst is slightly pointed at the apex. Cingulum and sulcus clearly delineated. The parasutures are marked by slender processes, which are interconnected along their length to give a variable reticulum. On the ventral surface, the processes are shorter and the distal connections more irregular. Length: 61-80 µm, breadth 55-74 µm. Processes about 10 µm in length.
