Tetrachacysta granulata

granulata (Jiabo, 1978, p.94, pl.6, figs.7–8) Mao Shaozhi et al., 1999, p.158.  Holotype: Jiabo, 1978, pl.6, fig.7.  Originally Dinogymnium, subsequently Microdinium, thirdly Dinogymniopsis, fourthly (and now) Tetrachacysta.  Mao Shaozhi et al. (1999, p.158) attributed this species to Gao Ruiqi et al. (1992a), but clearly intended Dinogymnium granulatum Jiabo 1978 and gave a full citation for the correct basionym.  Age: Early Tertiary.

Parent: Tetrachacysta
