| Summary: | The end-Triassic mass extinction (ETE) is one of the biggest biotic crises that has occurred during geological history and the main cause is generally attributed to the emplacement of the Central Atlantic Magmatic Province (CAMP) ~201.51 million years ago. The ETE was the most devastating extinction for the so-called Modern Fauna and the triggering mechanisms associated with the ETE, such as global warming, ocean acidification, ocean anoxia and sea-level changes, are analogous to imminent environmental perturbations. The amount of CO? injected into the atmosphere during each CAMP magmatic pulse rivals anthropogenic CO? emission projected for the 21st century. Although the ETE and its aftermath are well documented, the conditions leading up to the ETE remain poorly understood. Yet, most recent studies emphasize the complexity of the pre-extinction scenario and the importance of deciphering precursor events to the ETE if the mechanisms for this "Big 5" mass extinction are to be fully delineated.
