I found this out there on the PETM (LPTM, IETM).

"Sediments recovered above and below the P/E boundary allow the study of the biotic evolution associated with the P/E boundary . Planktonic foraminiferal “excursion fauna” were found to have been present in the equatorial Pacific in the Paleocene prior to the P/E event but only became abundant elsewhere during the global warming associated with the P/E boundary, while nannofossil extinctions previously associated with the event actually occurred above it.
Thoracosphaera cysts, representing a disaster flora found at the K/T boundary, were found in the Leg 199 P/E boundary intervals."

I think the last sentence is revealing. There are species out there, ready to take advantage of whatever happens.
