atavum (Naumova, 1968, p.38, pl.2, fig.11) Fensome et al., 1990, p.85. Holotype: Naumova, 1968, pl.2, fig.11. Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium. Since Naumova (1968), in a citation in her plate caption, referred to this species as Baltisphaeridium atavum, Fensome et al. (1990, p.85) validated the combination since this Cambrian species is clearly not assignable to Hystrichosphaeridium. Age: Cambrian.
Parent: Baltisphaeridium
