Great Debate on Great Extinctions
Convener: Nicholas T. Arndt  | Co-Convener: Helmut Weissert 
Tue, 25 Apr, 15:30–17:00

This Great Debate addresses the cause of mass extinctions, in particular the relative importance of meteorite impacts as opposed to other events.

Public information: Although every science journalist is convinced that the Chicxulub meteorite was the sole cause of the extinction of the dinosaurs, many geoscientists are not so sure. All of the major extinctions that punctuate earth history are associated with short periods of intense volcanism and only the end-Cretaceous extinction is also coincident with meteorite impact. The causes of all mass extinctions will be debated by a panel of experts:

Paul Renne, Berkeley Geochronology Center

Paul Wignall, Leeds University

Blair Schoene, Princeton University

Evelyn Kustatscher, Naturmuseum Südtirol

Christian Koeberl, Natural History Museum Vienna
