Batioladinium exiguum
From Fensome et al., 2019:
Batioladinium? exiguum (Alberti, 1961, p.26–27, pl.5, fig.14) Brideaux, 1975, p.1240. Holotype: Alberti, 1961, pl.5, fig.14.
Originally Broomea, subsequently (and now) Batioladinium?, thirdly Necrobroomea, fourthly Imbatodinium.
Questionable assignment: Brideaux (1975, p.1240). Lentin and Williams (1993, p.58) retained this species in
Batioladinium. Below (1990, p.53) suggested that this species may be a taxonomic synonym of Batioladinium? (as
Necrobroomea) pelliferum. Age: early Hauterivian–?late Barremian.
---------------------------------------------------------------------------------------------------
Original description as Broomea exigua: [Alberti, 1961, p. 26]: (Translation: LPP):
Description:
Shell flattened, outline nearly oval, often with irregular bulges. Epitheca more conical than the smaller hypotheca, antapex blunted. Apical horn short, sharp delimited. The two antapical horns are very short, usually unequal, ends blunted. Shell surface rough. Pylome and girdle questionable.
Dimensions:
Holotype - 74 µm, breadth 39 µm, length of antapical horns 3 and 5 µm, apical horn 12 µm.
Affinities:
Broomea exigua differs from B. jaegeri in the stoudy outline of the shell, and the shape of the antapical horns. The apical horn of B. exigua is much shorter.
