Gochteodinia imbatodinensis
Gochteodina imbatodinensis (Vozzhennikova, 1967, p.55, pl.12, figs.4a–c) Below, 1990, p.48. Emendation: Lentin and Vozzhennikova, 1990, p.91–92, as Protobatioladinium imbatodinense.
Now Protobatioladinium. Originally Imbatodinium, subsequently Necrobroomea?, thirdly Pareodinia, fourthly Pareodinia?, fifthly Batioladinium, sixthly (and now) Protobatioladinium, seventhly Gochteodinia. Lentin and Williams, 1993, retained this species in Protobatioladinium Nohr-Hansen, 1986, since Below, 1990, did not examine the holotype of this species.
Holotype: Vozzhennikova, 1967, pl.12, fig.4a; Lentin and Vozzhennikova, 1990, pl.11, figs.9-11; text-fig.50
Locus typicus: W Siberia, Russia
Stratum typicum: Late Jurassic
Translation Vozzhennikova, 1967: Lentin and Vozzhennikova, 1990
Original description: Vozzhennikova, 1967, p. 12: Imbatodinium imbatodinense
Theca pyriform Epitheca two to two and one half times as big as the hypotheca and terminating in an apical process which gradually tapers towards its distal end hypotheca with two equal, broadly rounded antapical processes Transverse furrow shallow It has not been possible to discern the position of the longitudinal furrow because of the poor preservation of the material, Envelope uniformly covered with small tubercles.
