Earth and environmental sciences professors Linda Ivany and Christopher Junium were among a group of scientists whose research published in PNAS shed light on how the Chicxulub impact 66 million years ago resulted in extinction of 75 percent of animals on Earth, including the dinosaurs. The team’s results were featured in Phys.org, BBC, Daily Mail, Newsweek, SciTechDaily, Earth.com, The Independent and more.
