"... The recurring

eccentricity, stimulated the occurrence and intensity of wet phases. It also highlights the possibility
that the Carnian Pluvial Event, although most likely triggered by enhanced volcanic activity, may also
have been modified by an orbital stimulus. ..."

during those intervals the monsoonal activity was strong enough to prevent the playa system from
drying out completely.

in distribution area, red beds became common, and surviving plants were walchian
conifers, peltasperms and other advanced gymnosperms, indicating an overall drying

"... Our reconstructions show that terrestrial vegetation collapse during the PTME,

carbon sequestration and chemical weathering, leading to limited drawdown of greenhouse gases.
This led to a protracted period of extremely high surface temperatures, during which biotic
recovery was delayed for millions of years. ..."
