Paleontologist Richard Fortey has just left the stage, taking his trilobite fossil with him.
What are trilobites? These days, they're museum objects. And museums, Fortey says, 'are there as proof of what we have done to the planet, as archives for the conscience of humanity'.
Moving on to talk about mass extinctions, Fortey alludes to the Yucatán peninsula, Mexico, where the Chicxulub crater can be found. The crater marks the largest confirmed impact on earth by an asteroid, coinciding with the transition between the Cretaceous and Paleogene periods in Earth's history, and believed to have caused the mass extinction of the dinosaurs.
The Chicxulub crater was suggested by David Blandy as an 'Extinction Site' to be plotted on the Extinct.ly world map.
