Neptune Space-Time plot

Occurrence data from Neptune plotted in space and time

Alternatives - Range chart plot :: Tabulate ranges from a site :: to see sites on a map plot, and sample details, use links in graphed output

Fossil Group:
Taxon to plot:
Plot interval:

Age bin: Latitude bin:
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
