*capricornum (Cookson and Eisenack, 1965a, p.128–129, pl.15, figs.1–9) Stover and Williams, 1995, p.107. Emendation: Stover and Williams, 1995, p.107, as Cooksonidium capricornum. Holotype: Cookson and Eisenack, 1965a, pl.15, fig.7; Fauconnier and Masure, 2004, pl.7, figs.7–10. Originally Cordosphaeridium, subsequently Systematophora?, thirdly Areosphaeridium, fourthly (and now) Cooksonidium. Taxonomic senior synonym: Hystrichosphaeridium (now Areosphaeridium) dictyostilum, according to Sarjeant (1981, p.115–116) — however, Lentin and Williams (1985, p.26) retained Cooksonidium (as Areosphaeridium) capricornum. Age: late Eocene.
