Some Dinosaur Groups Diminishing Before Mass Extinction: Live Chat with Museum Scientists

On May 10, the American Museum of Natural History and Wired Science hosted a live webcast discussion about new research on dinosaur extinction. The study shows that some dinosaur groups were already on the decline around the time an asteroid hit at the end of the Cretaceous.
Brandon Keim, an associate editor at Wired Science, moderated the discussion with two of the paper's co-authors: Mark Norell, chair of the Museum's Division of Paleontology, and Steve Brusatte, a Columbia University graduate student affiliated with the Museum's Division of Paleontology. Norell and Brusatte also answered questions submitted through email and Twitter.
