Kamptnerius


Classification: Mesozoic -> Arkhangelskiales -> Kamptneriaceae -> Kamptnerius
Sister taxa: Crucicribrum, Gartnerago, Kamptnerius, Senilatus,

Distinguishing features: Tiered placoliths with broad rim that has an asymmetric flange forming a wing and narrow central area spanned by a perforate plate. Typical kamptneriacean LM image with a narrow, dark outer-cycle; a diagnostic, bright median-cycle; a dark, inner-cycle; and a dark central area plate.
