Necrobroomea exigua
Necrobroomea exigua (Alberti, 1961) Wiggins, 1975
Now Batioladinium?. Originally Broomea, subsequently (and now) Batioladinium?, thirdly Necrobroomea, fourthly Imbatodinium.
Below, 1990, gave the citation, "Necrobroomea exigua (Alberti 1961) comb. nov."
Lentin and Williams, 1993, questionably retain this species in Batioladinium.
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
Translation Alberti, 1961: LPP
Original description: Alberti, 1961, p.26: Broomea exigua
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 Ám, breadth 39 Ám, length of antapical horns 3 and 5 Ám, apical horn 12 Ám.
Affinities:
Alberti, 1961, p.26: Broomea exigua
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.
