Hystrichosphaeridium sahii
From dinoflaj2
?sahii Lentin and Williams, 1993, p.331. Holotype: Sah et al., 1970, pl.2, fig.16. Originally Hystrichosphaeridium robustum (name illegitimate), subsequently (and now) Hystrichosphaeridium sahii. Questionable assignment: Masure and Foucher in Fauconnier and Masure (2004, p.313) as a problematic species. This is the substitute name for Hystrichosphaeridium robustum Sah et al., 1970, p.146, pl.2, figs.16-17 (an illegitimate name). Jain (1982, p.52) recommended that this species be restricted to the holotype. Age: Late Cretaceous.
