The Early Jurassic is marked by two of the largest global change events in Earth history, the Triassic-Jurassic mass extinction (at ~201 Ma) and the Toarcian Oceanic Anoxic Event (T-OAE; at ~183 Ma). These events appear temporally linked to emplacement of the Central Atlantic Magmatic Province (CAMP) and Karoo-Ferrar Large Igneous Province, respectively, but causality is still poorly constrained.

Here, I will present new data for both the Triassic–Jurassic mass extinction and the T-OAE and discuss coeval climatic/environmental change and their possible link to LIP volcanism at those times.
