Paleocene-Eocene Thermal Maximum

Any reason for no -55M peak here either? Regards, Mattjs 04:16, 21 February 2007 (UTC)

The PETM was (probably) an extinction event for certain benthic taxa, but for most genera it was basically a non-event, and overall doesn't rise above background here. The earliest Eocene, following the PETM, is actually a period of significant radiation rather than one of extinction. Dragons flight 06:44, 21 February 2007 (UTC)

Not being an expert I figured there was a good reason. My interest was its obvious relevance to global warming today. Mattjs 17:06, 22 February 2007 (UTC)
