twistringiensis ([[Maier, 1959]], p.308-309, pl.30, figs.3-4) [[Fensome et al., 1990]], p.639.  Holotype: [[Maier, 1959]], pl.30, fig.3; [[Sarjeant, 1983]], pl.5, fig.3.  Originally [[Galea twistringiensis|Galea]] (generic name illegitimate), subsequently [[Baltisphaeridium twistringiense Appendix A|Baltisphaeridium]] (Appendix A), thirdly [[Areoligera twistringiensis|Areoligera]], fourthly (and now) Spiniferites.  Taxonomic junior synonyms: (at specific rank) [[Hystrichosphaera ramosa var. multibrevis|Hystrichosphaera ramosa]] var. [[Hystrichosphaera ramosa var. multibrevis|multibrevis]] (subsequently [[Spiniferites multibrevis]]), according to [[Sarjeant, 1983|Sarjeant (1983]], p.94-95); [[Achomosphaera cambra|Achomosphaera]] (al. [[Spiniferites cambrus|Spiniferites]]) [[Achomosphaera cambra|cambra]], by implication in [[Jain, 1982|Jain (1982]], p.51), who considered this species to be a taxonomic junior synonym of [[Hystrichosphaera ramosa var. multibrevis|Hystrichosphaera ramosa]] var. [[Hystrichosphaera ramosa var. multibrevis|multibrevis]] (as [[Spiniferites ramosus subsp. multibrevis|Spiniferites ramosus]] subsp. [[Spiniferites ramosus subsp. multibrevis|multibrevis]]).  According to [[Fensome et al., 1990|Fensome et al. (1990]], p.639): "The species name [[Galea twistringiensis]] is validly published even though the generic name [[Galea twistringiensis|Galea]] is illegitimate; see I.C.B.N. Article 68.1[Article 55.1 in the 1994 I.C.B.N.].  [[Lentin and Williams, 1985|Lentin and Williams (1985]], p.140,333) and [[Lentin and Williams, 1989|Lentin and Williams (1989]], p.347) brought together the synonymies proposed by [[Jain, 1982|Jain (1982]]) and [[Sarjeant, 1983|Sarjeant (1983]]), but also accepted the elevation of the variety (and later subspecies) 'multibrevis' to specific rank as [[Spiniferites multibrevis]].  [[Lentin and Williams, 1985|Lentin and Williams (1985]],[[Lentin and Williams, 1989|1989]]) considered the epithet 'multibrevis' to be senior.  Since the latter epithet was not raised to specific rank until [[Below, 1982c|Below (1982c]], p.35) did so, the epithets 'twistringiensis' (validly published in 1964) and 'cambrus' (erected in 1970) are both senior to 'multibrevis' at specific rank.  Thus, following the synonymies cited above and considering this taxon at specific rank, the correct name is Spiniferites twistringiensis ....  The specific epithet has commonly been misspelled 'twistringense'." Age: Mid Miocene.
