Batioladinium pelliferum
Batioladinium? pelliferum, (Alberti, 1961), Brideaux, 1975
Originally Broomea, subsequently (and now) Batioladinium?, thirdly Imbatodinium, fourthly Necrobroomea.
Tax. jr. synonym of Batioladinium micropodum (Eisenack and Cookson, 1960) Brideaux, 1975, according to Wiggins, 1975. Dörhöfer and Davies, 1980, retained Batioladinium? pelliferum as a separate species. At the time of the transfer, Brideaux, 1975, questionably included this species in Batioladinium.
Below, 1990, suggested that Batioladinium? (as Necrobroomea) exiguum (Alberti, 1961) Brideaux, 1975, may be simply a smooth variant of this species.
Below, 1990, transferred this species to Necrobroomea Wiggins, 1975. Lentin and Williams, 1993, questionably retained the species in Batioladinium.
Holotype: Alberti, 1961, pl.5, fig.11
Locus typicus: Haverlahwiese near Salzgitter, Germany
Stratum typicum: Late Barremian-Early Aptian

Original description as Broomea pellifera: [Alberti, 1961, p. 26]: (Translation: LPP):
Description:
Shell flattened, outline nearly oval. The usually slightly larger epitheca is more conical than the at the apex rounded hypotheca.
Apical horn short and sharply delimited. Two short, blunt, antapical horns of unequal length, one +/- reduced.
Surface of shell, inclusive horns, covered by a fur-like ornamentation. Transverse-furrow and pylome not observed.
Dimensions:
Holotype: length 77 µm, breadth 38 µm, length of 1. antapical horn 7 µm, 2. c. 2.5 µm.
Range: Length of shell 68-70 µm, breadth 31-37 µm.
Affinities:
B. pellifera differs from B. jaegeri in the well rounded antapex and the fur-like ornamentation of the shell.
