"capricornum" (Cookson and Eisenack, 1965a, p.128-129, pl.15, figs.1-9) Stover and Evitt, 1978, p.20. 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. NOW Cooksonidium. Originally Cordosphaeridium, subsequently Systematophora?, thirdly Areosphaeridium, fourthly (and now) Cooksonidium. Taxonomic senior synonym: Hystrichosphaeridium (now Enneadocysta?) dictyostilum, according to Sarjeant (1981, p.115-116) - however, Lentin and Williams (1985, p.26) retained Areosphaeridium (now Cooksonidium) capricornum. Age: Late Eocene.
