[edit] Summary

Description This image shows the 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.

Colour code:

  • 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.
