Nannotax3 - ntax_main - Lotharingius hauffii

Citation: Lotharingius hauffii Grün&Zweili in Grün et al., 1974

Synonyms: Bennocyclus decussatus Zweili and Grün in Grün et al., 1974 [according to Bown (1987)]

Distinguishing features:
Parent taxon (Lotharingius): Elliptical watznaueriacean coccoliths typically with central-area axial cross, with or without additional lateral bars. Cross usually spine bearing. Extinction figure with nearly straight arms.
This taxon: Small (2.5-4µm), broadly elliptical Lotharingius ; central area narrow with spine-bearing axial cross.

Geological Range:
Last occurrence (top): within NJ12a subzone (164.63-165.71Ma, top in Callovian stage). Data source: Bown & Cooper 1998
First occurrence (base): at base of NJ5a subzone (0% up, 186.3Ma, in Pliensbachian stage). Data source: Bown & Cooper 1998 (fig 4) - zonal event
