This conference will be the fourth of an informal series of meetings on mass extinctions and global catastrophes, including the geological and biological consequences of large-scale impact events. Various mass extinctions, of different degrees, mark some of the geological boundaries. These have been studied in the past, but only recently has there been a discussion on how short the timescale of these mass extinctions really was. For example, recent studies of the most profound extinction event in Earth's history, at the end of the Permian, indicated a much shorter time frame for this event than earlier data had suggested, with significant associated geochemical anomalies.
