Cyclagelosphaera baticlypeata

Classification: Mesozoic -> Watznaueriales -> Watznaueriaceae -> Watznaueria -> Cyclagelosphaera baticlypeata
Sister taxa: W. barnesiae, W. bayackii, W. fossacincta, W. manivitiae, W. ovata, W. britannica, W. reinhardtii, W. biporta, W. cynthae, W. contracta, W. okadai, W. quadriradiata, W. fasciata, W. rawsonii, C. baticlypeata, W. sp.,

Distinguishing features: Watznaueria with broad central-area spanned by radial bars


Citation: Cyclagelosphaera baticlypeata Bukry 1969
Rank: Species
Notes & discussion: This species should be probably be reclassified in Watznaueria since it is clearly elliptical rather than circular. Alternatively the genus Coptolithus could be used for Watznaueria specimens with grills but this does not seem a satisfactory option since there is little similarity between the central grills of W. rawsonii, W. fasciata and C. balticlypeata.
