Evidence Maps Tsunami After Dinosaur-killer Meteor Strike

Michigan Researchers Map Tsunami Impact on the Ocean Floor

University of Michigan researchers have been able to map what happened when a miles-wide asteroid collided with Earth about 66 million years ago and wiped out dinosaurs and other species. According to information published at, the catastrophic crash, resulting tsunami and intense cloud cover worldwide wiped out the dinosaurs and 75% of the the plants on the planet. The consequences made major changes to the planet’s composition and weather while leaving behind a 62-mile-wide crater.

The results of that seminal event in world history included destruction on a massive, unparalleled scale that included miles-high waves that affected the composition of the ocean floor for miles away, which researchers were able to track using advanced imaging and analysis technologies. The crater remains on the Yucatán Peninsula, but the tsunami disturbed ocean sediments halfway around the world to provide a distinctive footprint.
