Nannotax3 - ntax_mesozoic - Senilatus zipperum

Senilatus zipperum


Classification: ntax_mesozoic -> Arkhangelskiales -> Kamptneriaceae -> Senilatus -> Senilatus zipperum
Sister taxa: S. zipperum

Distinguishing features:
Parent taxon (Senilatus): Simlar to Gartnerago but rim with only 3 tiers and outline elongate-hexagonal rather than elliptical
This taxon: Numerous small pores in central plate, in LM the rim goes into extinction in 6 bloakcs corresponding to the sides of the hexagonal coccolith
