Recent Events in Science Asteroid That Killed the Dinosaurs Also Affected other Reptiles Read All About It! The asteroid collision widely thought to have killed the dinosaurs also led to extreme devastation among snake and lizard species, according to new research. "The asteroid event is typically thought of as affecting the dinosaurs primarily," said Nicholas R. Longrich, a postdoctoral associate with Yale's Department of Geology and Geophysics and lead author of the study. "But it basically cut this broad swath across the entire ecosystem, taking out everything. Snakes and lizards were hit extremely hard." The study was scheduled for online publication the week of Dec. 10 in the Proceedings of the National Academy of Sciences. www.sciencedaily.com/releases/2012/12/121210160842.htm
