Indosphaera bhujensis
Indosphaera bhujensis Kumar, 1986
Holotype: Kumar, 1986b, pl.3, fig.5; Fensome et al., 1993a, fig.2 - p.973.
Locus typicus: Kachchh, western India; Middle Member, Jhuran Formation
Stratum typicum: Early Kimmeridgian-Tithonian
Original diagnosis: Kumar, 1986, p.392
Proximate, pentagonal ovoidal cyst, with an apical horn and with or without two short antapical protrusions. Paratabulation is indicated by a faintly marked paracingulum in the form of ridges on the autophragm. Archaeopyle is not developed. The autophragm is thin, psilate to scabrate.
Original description: Kumar, 1986, p.392
These are proximate, pentagonal ovoidal, short apical hom and the antapical end is generally rounded and smooth, but it may also be undulating or have two antapical protrusions. Paratabulation features are lacking, but frequently the paracingulum is marked by the presence of low irregular and discontinuous ridges on the autophragm. A distinct archaeopyle is not seen. The autophragm is thin, psilate to scabrate and shows ridges in the paracingular region.
Size: Range of 10 specimens: length 42-71 Ám, width 31-52 Ám.
