Impagidinium inaequalis

inaequalis (Wall and Dale in Wall et al., 1973, p.22, pl.1, figs.7–8) Londeix et al., 2009, p.68.  Holotype: Wall et al., 1973, pl.1, figs.7–8.  Originally Spiniferites, subsequently (and now) Impagidinium.  Londeix et al. (2010, p.204) corrected an error to the basionym citation in Londeix et al. (2009), but the combination was still validated in the latter reference.  Age: Holocene.

Parent: Impagidinium
