Praussia ephemera
Praussia ephemera (Prauss, 1989, p.23–24, pl.5, figs.11–12,15–18; text-fig.6) Williams et al., 1998, p.507.
Originally Hyalosphaera (generic name illegitimate), subsequently (and now) Praussia.
Holotype: Prauss, 1989, pl.5, fig.11, text-fig.6
Locus typicus: Well BG SPD 10, Germany
Stratum typicum: Late Toarcian, Levesquei Zone
Translation Prauss, 1989: LPP
Original diagnosis: Prauss, 1989, p. 23
Cyst habit skolochorate/cavate. Wall consisting of pedium and tectum. Endoblast spheroidal, psilate; periblast obovoidal, psilate. Areation due to finitely arranged, long, thin, acuminate processes, which are broadened at the bases and interconnected by low seams or strips. Delicate scabrae are arranged in a peniareate position. The sulcal region is, where discernable, typically developed complexly. At the apex there is a coarser, granulate structure.
Dimensions: endoblast periblast
l: 40,3 µm: 45,7 µm
b: 37,0 µm: 48,0 µm
