Tubotuberella vozzhennikovae (Sarjeant, 1982) Jan du Chêne et al., 1986
Originally Gonyaulacysta, subsequently (and now) Tubotuberella.
Questionable tax. jr. synonym of Tubotuberella sphaerocephalis Vozzhennikova, 1967, according to Brenner, 1988, who in the same publication (p.92) listed Tubotuberella sphaerocephalis as a tax. jr. synonym of Tubotuberella (now Gonyaulacysta) eisenackii (Deflandre, 1938) Stover and Evitt, 1978. Because of the uncertainty concerning Brenner"s intentions, Lentin and Williams, 1993 retain Tubotuberella vozzhennikovae as a separate species.
Holotype: Sarjeant, 1982, pl.8, fig.9
Age: Early Oxfordian
