The Cretaceous\u2013Paleogene extinction was the last great extinction event to occur on Earth, and is most notable for causing the diversification of mammals that eventually resulted in\u00a0<em>Homo sapiens<\/em>.<\/p>\n<p>66 million years ago an asteroid roughly 15 kilometers (9 miles) wide hurtled into Chicxulub, Mexico. The collision, which left behind a 180-kilometer (110-mile) crater, released 420 zettajoules of energy \u2014 100 teratonnes of TNT, or roughly two million times stronger than the largest thermonuclear device ever used (the Russian Tsar Bomba). The impact created a huge dust cloud that blocked out the Sun, starting the extinction ball rolling by killing off much of the world\u2019s plants, and thus the herbivores soon after. Due to high levels of oxygen in the Cretaceous atmosphere, the impact may also have caused intense, global firestorms that killed off many other species. Because the asteroid landed in the ocean, megatsunamis would\u2019ve swept the world\u2019s coasts, too.<\/p>\n<p>Until now, though, there hasn\u2019t been enough evidence that the Chicxulub impact actually<em>caused\u00a0<\/em>the Cretaceous-Paleogene extinction.<\/p>\n<p>[ <a href=\"http:\/\/www.extremetech.com\/extreme\/147978-finally-confirmed-an-asteroid-wiped-out-the-dinosaurs\" target=\"_blank\">click to continue reading at ExtremeTech<\/a> ]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>from ExtremeTech Finally confirmed: An asteroid wiped out the dinosaurs By\u00a0Sebastian Anthony A team of American and European researchers have confirmed that the Cretaceous-Paleogene extinction \u2014 the event that wiped out roughly 75% of the planet\u2019s species, including almost every dinosaur \u2014 was caused by an asteroid impact in Mexico 66 million years ago.
