Nannotax Range Chart plotter
Taxa to plot:
Separate names with a semi-colon ";". Names can be abbreviated and % used as wildcard(E.g. %hantken;Clavig; Cocc% pel%), but names must be at least 5 characters long. By entering a string of species names you can plot exactly the set of species you want, alternatively enter generic names to see data for all species within them.
Data to plot: Mikrotax range-bar?
:: Neptune data?
:: Diversity plots?
Blue histograms or spindle diagrams plot frequency of occurrence of the taxon (and synonyms) in the Neptune database.
Range boxes show the ranges recorded on this website
Pink - interval within which LAD occurs
Green - interval within which FAD occurs.
Hold cursor over plot to get 'tool tip' info on colours and plotted values.
- Neptune does not really have enough data in the Cretaceous to be very reliable. Likewise some ranges from the website are only rough estimates.
