Fentonia
From Williams et al., 2017:
[Fentonia, Bailey and Hogg, 1995, p. 58
Acritarch genus.
Tax. sr. syn.: Limbicysta (Appendix A), according to MacRae et al. (1996, p.1479). Nomenclatural junior synonym: Neofentonia (Appendix A). Özdikmen (2009, p.234) considered Fentonia Bailey and Hogg, 1995 to be illegitimate because it is a junior homonym of Fentonia Butler 1881; however, Fentonia Butler 1881 is an animal and under the I.C.N. it does not pre-empt Fentonia Bailey and Hogg.
Type species: as Parvocysta bjaerkei, Smelror, 1987 (fig.4G)] ; Fentonia bjaerkei, emend. Bailey and Hogg, 1995
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Bailey and Hogg, 1995]:
Diagnosis:
Small to medium sized, single-walled, dorsoventrally compressed palynomorphs with a prominent apical protuberance and bilateral symmetry. Four lateral protrusions arise, separated by a mid lateral constriction. Antapex between posterior process elements flat or mildly concave. Conspicuous folds may be present in the apical region oriented apically-antapically. Excystment aperture not developed.
