Summary

Description
English: This image shows the marine biodiversity during the Phanerozoic. Note that this is a result of changes in both the rate of extinctions and the rate of new originations. The Dresbachian extinction event in particular is obscured by nearly immediate replacement with new genera.

  • grey: total known genera from Sepkowski's catalogue (cited by Rohde & Muller)
  • green: "well-defined genera", i.e. known genera excluding those represented by "single occurrences" and those whose dates are uncertain.
  • red: trend for "well-defined genera". Dereived by fitting a third-order polynomial to the data.
  • yellow: the "Big Five" mass extinctions.
  • blue: other extinction events.
