Praecalcigonellum polymorphum
From dinoflaj2
*polymorphum (Keupp, 1980a, p.128,130-131, pl.15, figs.7-15; pl.16, figs.1-6) Lentin and Williams, 1993, p.538. Holotype: Keupp, 1980a, pl.15, figs.7-8. Originally Calcigonellum, subsequently (and now) Praecalcigonellum. This combination was not validly published in Keupp and Versteegh (1989, p.211,218, pl.2, fig.10), since these authors did not fully reference the basionym. Age: late Aptian-Early Albian.
Parent: Praecalcigonellum
