In the December Scientific American paleontologist Stephen Brusatte of the University of Edinburgh delves into one of the greatest scientific mysteries of all time: the extinction of the dinosaurs. In an attempt to solve it he and his colleagues analyzed all the latest evidence using cutting-edge techniques. What they found may surprise you. (Hint: the famous asteroid impact played a role, but it’s not the whole story.) To learn more about the rise and fall of the dinosaurs, check out Brusatte’s lecture in the video below.
