Volcanic Activity Caused Mass Extinction Before Dinosaurs Arrived, New Study Finds

Before the dinosaurs roamed the earth, a number of other species did — including other large sea reptiles and mollusks. But they abruptly died off about 200 million years ago, marking the end of the Triassic period, one of five major extinction events that scientists have identified throughout Earth’s history. Today, an international team scientists from MIT, Colombia, Rutgers, and other prestigious universities in Canada and Morocco released what they say is the best evidence that a series of powerful volcanic eruptions caused this mass extinction event, which opened the door for the dinosaurs to take over millions of years later.
