![]() ![]() As a result, 4 out of 5 mass extinctions coincided with the formation of ‘flood basalt’, a large igneous rock formed by volcanic eruptions. ![]() The research team used the supercomputer ‘Dartverse Discovery Cluster’ to quantitatively analyze the association between volcanic eruptions and extinctions that are believed to have had a major impact on Earth. Representatively, the ‘asteroid impact theory’, which states that a comet or asteroid collided with the earth, causing rapid changes in the global environment and leading to mass destruction, and the ‘volcanic explosion theory’, which claimed that volcanic ash, dust, and gas caused rapid climate change due to a large-scale volcanic eruption, have been fiercely opposed. The cause of the extinction of dinosaurs at the end of the Cretaceous period 66 million years ago has long been a controversial topic in paleontology. It is noteworthy as a result of directly refuting the theory of dinosaur extinction due to an asteroid impact that has been raised so far.Ī research team from Dartmouth University in the United States published the results of a study so far that there is a link between major volcanic eruptions and mass conversion of species in the Proceedings of the National Academy of Sciences of the United States (PNAS) on September 12 (local time). Courtesy of Brehin KellerĪnalytical results support the claim that dinosaurs became extinct due to volcanic activity. Flood basalt is a stepped topography formed by large volcanic eruptions. ![]() Researchers at Dartmouth University in the United States have suggested flood basalt areas as evidence that volcanic eruptions contributed to the extinction of dinosaurs. ![]()
