New research uncovers the significant role of Deccan Plateau volcanic eruptions towards the end of the Maastrichtian era in environmental toxicity that led to a mass extinction event 66 million years ago. With 70% of lavas erupting before the Cretaceous-Paleogene boundary, these findings reshape the understanding of ancient volcanic impact. Recent findings shed light on India's Deccan Plateau, where researchers have determined a substantial volcanic eruption near the end of the Maastrichtian era contributed immensely to the environmental changes 66 million years ago. This insight redefi... [836 chars]
