They’re not dinosaurs, but I think those will eventually be found, too.”

Within 45 minutes to an hour, thousands of tiny glass beads formed by the impact began to rain down on the site. Some of these beads, called tektites, were inhaled by the fish in the inland sea, according to a University of California Berkley news release about the study. The tektites would later be found stuck in the fishes' gills. Other tektites, zooming out of the atmosphere at 100 to 200 mph, landed in the mud left by waves from the inland sea. Others are thought to have caused wildfires across the entire continent...."
