Dinosaur extinctions related to the Jenkyns Event (early Toarcian, Jurassic)

: The early Toarcian Jenkyns Event (~183 Ma) was characterized by a perturbation of the global carbon cycle, global warming, which at continental areas led to intensifi ed chemical weathering, enhanced soils erosion, and intensifi ed wildfi res. Warming and acid rain aff ected diversity and composition of land plant assemblages, caused a loss of forests and thereby impacted on trophic webs. The Jenkyns Event, triggered by volcanic activity of the Karoo-Ferrar Large Igneous Province, changed terrestrial ecosystems
