mutterlosei (Keupp, 1979a, p.41, pl.10, figs.11-12; pl.11, figs.1-5) Lentin and Williams, 1993, p.538.  Holotype: Keupp, 1979a, pl.11, figs. 1-3.  Originally Calcicarpinum, subsequently Calcigonellum, thirdly (and now) Praecalcigonellum.  This combination was not validly published in Keupp and Versteegh (1989, p.218, pl.2, fig.11), since these authors did not fully reference the basionym.  Age: Early Barremian.
