Adnatosphaeridium caulleryi

Adnatosphaeridium caulleryi (Deflandre, 1939a, p.189, pl.11, figs.2-3) Williams and Downie, 1969, p.17.

EMENDATION: Stancliffe and Sarjeant, 1990, p.200, as Adnatosphaeridium caulleryi.

TYPE: Holotype: Deflandre, 1939a, pl.11, fig.2; Stancliffe and Sarjeant, 1990, pl.1, figs.3,5.

HISTORY: Originally Hystrichosphaeridium, subsequently Cannosphaeropsis, thirdly (and now) Adnatosphaeridium, fourthly Polystephanephorus. Stancliffe and Sarjeant (1990, p.200) retained this species in Adnatosphaeridium.

COMMENTS: This combination was not validly published in Williams and Downie (1966c, p.218), since these authors did not fully reference the basionym.

AGE: Early Oxfordian.
