Microdinium punctulatum
From Fensome et al., 2019:
Microdinium punctulatum Vozzhennikova, 1967, p.96, pl.37, figs.7a–b. Holotype: Vozzhennikova, 1967, pl.37, figs.7a–b; Lentin and Vozzhennikova, 1990, text-fig.61; lost according to Lentin and Vozzhennikova (1990, p.107). Originally (and now) Microdinium, subsequently Microdinium?. Questionable assignment: Stover and Evitt (1978, p.66) — however, Lentin and Vozzhennikova (1990, p.106) included the species in Microdinium without question. According to Lentin and Vozzhennikova (1990, p.107), no potential lectotype is available and the name should be restricted to the type. Age: ?Maastrichtian.
---------------------------------------------------------------------------------------------------
Lectotype: none available, according to Lentin and Vozzhennikova, 1990
Locus typicus: Kazakhstan
Stratum typicum: ?Maastrichtian
Translation Vozzhennikova, 1967: Lentin and Vozzhennikova, 1990
Original description: Vozzhennikova, 1967, p.96
Theca sphaerical, epitheca somewhat smaller than hypotheca. Arrangment of plates the same as in the type. Plates and edges of transverse furrow bordered by colored smooth, regular outgrowths. Surface of plates finely granular.
