Imbatodinium jaegeri
Imbatodinium jaegeri (Alberti, 1961) D÷rh÷fer and Davies, 1980
Now Batioladinium. Originally Broomea, subsequently (and now) Batioladinium, thirdly Necrobroomea, fourthly Imbatodinium.
Tax. sr. synonym of Pseudoceratium gochtii Pocock, 1962, according to C. Singh, 1971.
Below, 1990, stated that Batioladinium (as Necrobroomea) micropodum (Eisenack and Cookson, 1960) Brideaux, 1975, is a tax. sr. synonym of Batioladinium (as Necrobroomea) jaegeri, according to Davey, 1974. Davey, 1974, did not include the holotype of Batioladinium jaegeri in his synonymy listing for Batioladinium (as "Broomea ") micropodum.
Below, 1990, suggested that Batioladinium? (as Necrobroomea) gochtii (Alberti, 1961) Lentin and Williams, 1977, may be only a more distinctly granulate variant of this species.
Holotype: Alberti, 1961, pl.5, fig.2
Locus typicus: Haverlahwiese, Salzgitter, central Germany
Stratum typicum: Early Albian
Translation Alberti, 1961: LPP
Original description: Alberti, 1961, p.26: Broomea jaegeri
Diagnosis: Shell flattened, partly flat, its outline elongate, the sides convex, largest width mostly slightly below the equator. With a more or less offset, long apical process, which narrows towards the free end. Antapical horns short, pointed at the tips, slightly unequally long. Shell surface lightly granulate or smooth.
Dimensions: holotype: length 149 µm, width 37 µm, length of antapical horns around 7 µm. In other specimens the lenght varies betweeen 91 and 158 µm, the width between 26 and 40 µm. More than 25 specimens studied.
