Hystrichosphaeridium albertense
"albertense" Pocock, 1962, p.82, pl.15, figs.226–227. 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. NOW Oligosphaeridium. 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. Age: Barremian.
