Title: PETM dinoflagellates suffered plenty (Purdue university))
Post by: Pmt111500 on March 15, 2017, 07:01:16 AM
Marked decrease of dinoflagellate abundance during PETM observed. As oceans were this warm, it would mean vast areas of tropical continents were too hot for multicellular life at this time. I guess this would mean even the rains were too hot for plants. Sorry no link for the actual paper (partly based on models) but here's the press release and abstract about this. Note that the press release does not estimate the deviation from the preindustrial T.
