Scientists say that the asteroid produced tsunamis that spread thousands of miles from the site of the initial impact.
Did Volcanic Eruptions Drive Dinosaurs to Extinction?
"This tsunami was strong enough to disturb and erode sediments in ocean basins halfway around the globe, leaving either a gap in the sedimentary records or a jumble of older sediments," says Molly Range, an author of the study and an oceanographer at the University of Michigan, in aThe team first created a computer simulation of the impact and its immediate aftermath, including the creation of the impact crater and the start and spread of subsequent tsunamis.
The simulation states that within 24 hours of impact, the tsunamis had made their way through the majority of the Atlantic and the Pacific Oceans and had arrived in the Indian Ocean. Within 48 hours, these tsunamis waves had crashed against most of the world's coastlines.
