Adnatosphaeridium densifilosum
From Williams, Lentin and Fensome 1998 - Lentin and Williams Index of Fossil Dinoflagellates:
[Adnatosphaeridium densifilosum, (Cookson and Eisenack, 1974, p. 70, pl.24, fig.13), Stancliffe and Sarjeant, 1990, p. 201.
Originally Cannosphaeropsis, subsequently Cannosphaeropsis?, thirdly (and now) Adnatosphaeridium.
Holotype: Cookson and Eisenack, 1974, pl.24, fig.13; Stancliffe and Sarjeant, 1990, pl.4, fig.1.]
Occurrence: Broome Waterbore
Age: Late Jurassic-Early Cretaceous

Original description as Cannosphaeropsis densifilosa: [Cookson and Eisenack, 1974, p. 70]:
Diagnosis:
Central shell originally probably spherical, now deformed ovally, thin-walled, with a series of radially extending, fairly sturdy, cylindrical to slightly conical broadened support-members which, at approximately the same height, greatly branch out and break up into fine, thin branches. These enter in multi-fold connections with the thin branches of the adjacent propping-members in most manifold manner, whereby numerous secondary divisions and secondary connections occur also with areal widenings of the reticulation filaments.
Dimensions:
central shell about 70 x 52 µm, overall about 166 x 142 µm
Remarks:
The reticulation surrounding the central shell is very complicated and possibly an extreme in this genus. The dark body on the left-hand side of the photograph does not belong to the object.
