Taxonomy:

Citation: Lapideacassissp.
Synonyms: Pervilithus varians Crux 1981 - this is clearly a Lapideacassis but specific identification is not possible form the figured material [my interpretation - JRY 2015]

Farinacci & Howe catalog pages: Pervilithus varius *

Distinguishing features: Specimens not identified to species level


Morphology remarks: We are using this category for images of specimens which can be identified to generic level but have not been definitively assigned to a single species.

Geological Range:
Last occurrence (top): within (-Ma, top in "Holocene" stage). Data source:
First occurrence (base): within (-Ma, base in stage). Data source:

Plot of occurrence data:

  • Histogram - Neptune occurrence data from DSDP and ODP proceedings. Pale shading <50 samples in time bin. Interpret with caution & read these notes
  • Note to users in China - the diagram may not plot unless you use a VPN since I use google services on the website. If this is a problem please contact me 谢谢.
