Description

Biogeography and Palaeobiology

Most likely ancestor:
Trilobatus sacculifer - at confidence level 4 (out of 5). Data source: Kennett & Srinivasan 1983; Spezzaferri et al. 2015.

Biostratigraphic distribution

Geological Range:
Last occurrence (top): at top of PL6 [Atl.] zone (100% up, 1.9Ma, in Gelasian stage). Data source: Wade et al. (2011), zonal marker
First occurrence (base): in upper part of PL5 [Atl.] zone (71% up, 2.6Ma, in Piacenzian stage). Data source: Wade et al. (2011), additional event; position within zone determined by linear interpolation from data in table 1 of Wade et al. (2011).

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.
• Grey shading between taxa indicates intergrading species within an anagenetic lineage (data from Lamyman et al. 2026).
• Histogram - Neptune occurrence data from DSDP and ODP proceedings. Pale shading <50 samples in time bin. Interpret with caution & read these notes
