However, additional studies are needed to see how soils reacted to the PETM in other parts of the world.
But it fits with the controversial proposal that a comet impact caused the PETM. "The timing is nothing short of remarkable," said Schaller, who presented the discovery September 27.
Carbon dioxide in the atmosphere increased rapidly during the PETM period resulting in a sharp increase of about 5 to 8 degrees Celsius in global temperature.
"Our results suggest that future ocean acidification and possible effects on marine calcifying organisms will be more severe than during the PETM," Zeebe said.
Unlike the relatively mild interglacials driven by the tilt, wobble and orbit of the Earth, the PETM fundamentally transformed the planet.
Remarkably, there appears to be no relationship between the PETM and the diversification curve for terrestrial ferns.
The researchers examined rock cores from the Paleocene-Eocene Thermal Maximum (PETM) event that were collected in Spitsbergen, Norway.
'We knew the results were likely to show a decline in foram diversity but we weren't expecting such a seismic shift'.Forams record past events in the geological record -- in particular, the effect of the Palaeocene-Eocene Thermal Maximum (PETM), a period of massive carbon release and rapid warming, 55 million years ago, accompanied by extinctions in marine life.
