Short summary
A rare tropical record of the Paleocene–Eocene Thermal Maximum, a potential analog for future global warming, has been identified from post-impact strata in the Chicxulub crater. Multiproxy analysis has yielded evidence for increased humidity, increased pollen and fungi input, salinity stratification, bottom water anoxia, and sea surface temperatures up to 38 °C. Pollen and plant spore assemblages indicate a nearby diverse coastal shrubby tropical forest resilient to hyperthermal conditions.
