"SPINIFERITES subgenus HAFNIASPHAERA" (Hansen, 1977, p.13-14) Quattrocchio and Sarjeant, 2003, p.140. NOW Hafniasphaera. Originally (and now) Hafniasphaera, subsequently Spiniferites subgenus Hafniasphaera, We here retain Hafniasphaera as a genus on the basis of its distinctive morphology. Taxonomic senior synonym: Spiniferites, according to Stover and Williams (1987, p.117) - however, Edwards (1996, p.989) retained Hafniasphaera. Taxonomic junior synonym: Rivernookia, according to Lentin and Williams (1985, p.311).
