Scientists Think They Found Asteroid That Ended Dinosaurs On Earth

Scientists at a site in North Dakota believe they have found fragments of an asteroid that struck Earth about 66 million years ago off the Yucatan Peninsula, leading to the slow extinction of the dinosaurs.

When the asteroid struck, it sent molten debris into the air that later cooled into “glass spheres” that were discovered millions of years later at the North Dakota site known as Tanis, preserved in amber, according to the New York Times. Fragment tests show that not only did they contain unbroken rock, but also sections of limestone crust from the asteroid crater thousands of miles away. There were also high amounts of iron, nickel and chromium found in asteroid material. “Every stain removed from this beautiful clear glass is a piece of debris,” said Robert DePalma, an assistant professor and graduate of the University of Manchester, during a speech at NASA Goddard Space Flight Center this week, according to Times. “Seeing a piece of the culprit is just a boring experience.” Sorry, but this video failed to load. DePalma’s findings have not yet been peer-reviewed, but his supervisor, Professor Phil Manning, told the BBC he also believed the pieces came from the dinosaur-ending asteroid, according to people.com. “We were able to separate the chemistry and recognize the composition of this material,” Manning said. “All the data, all the chemical data from this study strongly suggest that we are examining a part of the percussion pendulum. of the asteroid that finished it for the dinosaurs “.
