Bosedinia microgranulosa
From Fensome et al., 2019:
Bosedinia microgranulosa (Jain, 1977b, p.176, pl.6, fig.74) Jansonius, 1989, p.67. Holotype: Jain, 1977b, pl.6, fig.74.
Originally Fromea (Appendix A), subsequently (and now) Bosedinia. Age: early Albian.
---------------------------------------------------------------------------------------------------
Original description: [Jain, 1977b]:
Fromea microgranulosa sp. nov.
PI. 6, fig. 74
Holotype - PI. 6, fig. 74; Slide no. 5053-38.
Locality - Kallakkudi Limestone Quarry II, Dalmiapuram, South India.
Horizon - Grey Shale Member, Dalmiapuram Formation; Early Albian.
Diagnosis - Shell spherical, surface ornamentation densely microgranulose, variously folded, mostly forming convolutions. Archaeopyle apical.
Measurements Holotype Range
Shell diameter 60 μm 45-70 μm
Comparison - F. microgranulosa sp. nov. differs from rest of the species of the genus in its surface ornamentation and constant convoluted foldings.
---------------------------------------------------------------------------------------------------
Transfer to Bosedinia by Jansonius, 1989:
"F. microgranulosa" Jain, 1977 (p.176, pl.6, fig.74) has a proportionally broad archeopyle with attached operculum and is here assigned to Bosedinia as B. microgranulosa (Jain) Jansonius, n. comb. Early Albian.
