Meiourogonyaulax bathonica

bathonica (Conway, 1978, p.349, pl.2, figs.4–5;7–8) Fensome and Williams, 2004, p.421. Holotype: Conway, 1978, pl.2, figs.4–5. Originally Lithodinia, subsequently (and now) Meiourogonyaulax. This combination was not validly published in Conway (1990, p.32) since that author did not fully reference the basionym. Age: late Bathonian.
