Broomea exigua
Broomea exigua, Alberti, 1961
Now Batioladinium?. Originally Broomea, subsequently (and now) Batioladinium?, thirdly Necrobroomea, fourthly Imbatodinium.
Below, 1990, suggested that this species may be simply a smooth variant of Batioladinium? (as Necrobroomea) pelliferum (Alberti, 1961) Brideaux, 1975.
Holotype: Albert, 1961, pl.5, fig.14
Locus tyicus: Bohrung Werle 3; Germany
Stratum typicum: Early Hauterivian

Original description: [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.
