Anthosphaeridium
From Fensome et al., 2019:
Anthosphaeridium, Cookson and Eisenack, 1968, p.115.
Fensome and Williams (2004) were incorrect in listing this as an acritarch genus. It's dinoflagellate affinity was confirmed by Schiøler and Wilson (1998, p323), who described an archeopyle for the type.
Type: Cookson and Eisenack, 1968, fig.4A, as Anthosphaeridium convolvuloides.
