krasheninnikovii (Bolli, 1974, p.856, pl.7, figs.1-5; pl.18, figs.10-12; pl.19, figs.1-12; pl.20, figs.1-4; pl.24, figs.1-2) Lentin and Williams, 1993, p.518. Holotype: Bolli, 1974, pl.7, figs.1-2; pl.18, fig.10; pl.24, fig.1. Originally Pithonella, subsequently Obliquipithonella, thirdly (and now) Pirumella. Willems (1992, p.160) considered Pithonella (now Pirumella) cookii, Pithonella (now Pirumella) bilamellata and Pithonella (now Pirumella) cylindrica to be possible taxonomic junior synonyms of this species. Fütterer (1990, p.540) and Willems (1992, p.160) also proposed this combination. Age: Coniacian-Santonian.
Parent: Pirumella
