Enrollment limited to 56. Impacts and Mass Extinctions. As the dinosaurs discovered sixty-five million years ago, it is not a pretty picture. Scientists now believe that such catastrophically violent collisions, apparently common in the past, are inevitable in the future as well. This course examines the role of impacts in earth history and the heated debate regarding the causes of mass extinctions.
