From Fensome et al., 2019:
Balcattia cirribarbata Cookson and Eisenack, 1982, p.48, pl.8, fig.15. Holotype: Cookson and Eisenack, 1982, pl.8, fig.15.
Age: late Albian–Cenomanian.
---------------------------------------------------------------------------------------------------
Original description: [Cookson and Eisenack, 1982] (translated form German):
Balcattia cirribarbata n. sp.
Plate 8, Fig. 15
Type: The specimen shown on Plate 8, Fig. 15, preserved in specimen Brickhouse Bore No. 3.
Diagnosis: A species of the genus Balcattia. The shell is (when complete) slightly oval and densely covered with irregularly coiled, branched appendages, which form a continuous network in the antapical region and extend quite far beyond the antapex. At the apex, a calotte has been raised along a fairly straight margin by the hatching process. The appendages extend beyond this margin.
Material and dimensions: 3 specimens. Type: Overall approx. 76 μ, from the apical margin including the antapical network 65 μ, width of the shell approx. 50 μ.
