Meiourogonyaulax predae
Meiourogonyaulax? predae Beju, 1971; Emendations: Drugg, 1978, p.64 and Below, 1990, p.45-46, both as Carpathodinium predae.
Now Carpathodinium. Originally Meiourogonyaulax?, subsequently Lithodinia?, thirdly (and now) Carpathodinium.
Beju, 1971, questionably included this species in Meiourogonyaulax.
Gocht, 1976, questionably transferred the species to Lithodinia Eisenack, 1935. Stover and Evitt, (1978, retained it in Meiourogonyaulax.
Holotype: Beju, 1971, pl.4, fig.4, text-fig.5
Locus typicus: Poiana Mare near Craiova, Romania
Stratum typicum: Callovian-Oxfordian
Translation Below, 1990: LPP
Original description: Beju 1971, p. 288-289
Diagnosis: Shell elongated ovoidal, epitract and hypotract almost isoradiametrical. When present, the apical horn is small and of triphid appearance. Shell wall thin, levigate. Tabulation: 4", 1a, 6"", 6c, 6""", 1p, 1"""": plate boundaries outlined by low and narrow crests. Cingulum relatively broad, slightly laevorotatory; sulcus of moderate width with a short epitractal section, broadening posteriorly. Archaeopyle formed by total or partial loss of apex.
Description: Shell wand about 1 Ám thick. When present, the apical horn is triangular in cross-section being made up by the elongated plates 1", 3", 4", but in most of the specimens seen the apex is lacking to form an archaeopyle with irregular margins. Six precingular plates are present, plates 6"" and 1" being reduced to accommodate an almost rhomboidal anterior intercalary plate. Cingulum 3-7 Ám wide, divided into six plates. Six postcingular plates are present, plate 1""" being elongated and reduced to accommodate a small posterior intercalary plate. The antapex formed by a large plate in form of a subspherical calotte which extends mostly on the ventral side.
Dimensions: Overall length: 56-74 Ám; overall width: 33-46 Ám.
