Citation: Eiffellithus windii Applegate & Bergen, 1988Rank: Species
Farinacci & Howe catalog pages: E. windii *
Distinguishing features: Small to medium sized species of Eiffellithus (<6.4µm) with a narrow central-area almost filled by diagonal cross-bars.
Morphology: The highest occurrence of E. windii is not well constrained (?Lower Hauterivian) but there is a definite switch in dominance from E. windii-types to E. striatus-types in the uppermost Valanginian/lowermost Hauterivian.
Most likely ancestor: Eiffellithus primus - at confidence level 2 (out of 5). Data source: Applegate & Bergen 1988.
Likely descendants: Eiffellithus striatus;

Geological Range:
Last occurrence (top): within NC4 zone (132.87-132.93Ma, top in Hauterivian stage). Data source: Bown et al. 1998
First occurrence (base): at base of BC4b subzone (0% up, 137.1Ma, in Valanginian stage). Data source: Bown et al. 1998 - zonal marker
Plot of occurrence data:
- Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
- Triangles indicate an event for which a precise placement has been suggested
- Histogram - Neptune occurrence data from DSDP and ODP proceedings. Pale shading <50 samples in time bin. Interpret with caution & read these notes
