albertense (Pocock, 1962, p.82, pl.15, figs.226-227) Davey and Williams, 1969, p.5. Holotype: Pocock, 1962, pl.15, fig.226; Brideaux, 1977, pl.11, figs.3-4; Jansonius, 1986, pl.4, figs. 4-5; Fauconnier and Masure, 2004, pl.55, figs.1-6. Originally Hystrichosphaeridium, subsequently (and now) Oligosphaeridium. Taxonomic junior synonyms: Hystrichosphaeridium (as Oligosphaeridium) irregulare, according to Jansonius (1986, p.213); Hystrichosphaeridium (as Oligosphaeridium?) coelenteratum, Hystrichosphaeridium (as Oligosphaeridium?) dispare and Hystrichosphaeridium (as Oligosphaeridium) reniforme, by implication in Stover and Evitt (1978, p.68-69), who considered these species to be taxonomic junior synonyms of Hystrichosphaeridium (as Oligosphaeridium) irregulare, which is now a taxonomic junior synonym of Hystrichosphaeridium (now Oligosphaeridium) albertense. This combination was not validly published in Davey and Williams (1966b, p.77), since these authors did not fully reference the basionym. Age: Barremian.
