Occurrence data from Neptune plotted in space and time

Fossil Group: Coccolithophores pf-Cenozoic pf-Mesozoic Nannos-Cenozoic Nannos-Mesozoic Radiolaria-cenozoic Diatoms
Taxon to plot:
Plot interval: Cenozoic Cretaceous Mesozoic Cenozoic+Cretaceous Late Cretaceous Paleogene Neogene Late Quaternary

Age bin: Latitude bin: 15 5 10 15 30 45 90
Species threshold: exclude samples with fewer species than this
Age anomaly threshold: exclude samples with anomaly score below this (approx equiv to proportion of non-anomalous taxa - e.g score of 0.7 means 70% of taxa recorded in sample are inside their expected range)

Notes

• If <40 samples box area is proportional to number of samples.
• Label is % of samples with the taxon.
• Hold cursor over plot to get 'tool tip' info on number of samples and bin co-ords.
• Colours are reds >80% ; oranges 30-79%; yellow 20-29%; pale brown 10-19%; grey <10%
• Click on % values (or Ma ages) to go to page with map of locations and listing of samples.
  
• BEWARE - Neptune does not really have enough data in the Cretaceous to be very reliable. For more explanation of the database and its limitations see - Neptune database introduction
