Scientists at the Berkeley Geochronology Center (BGC), the University of California, Berkeley, and universities in the Netherlands and the United Kingdom have issued a report in an article in the Journal Science [Science 8 February 2013: Vol. 339 no. 6120 pp. 684-687. DOI: 10.1126/science 1230492. Time Scales of Critical Events Around the Cretaceous-Paleogene Boundary.] in which they offer the resluts of their study of the events around the Cretaceous-Paleogene Boundary that led to the extinction of the dinosaurs. They offer more evidence that the impact of an asteroid or comet was at the least the death blow for dinosaurs 66 million years ago.
