Here is what the page “Ames Crater in Oklahoma Is 100 Million Years Younger Than Thought, Dating to a Mass Extinc” contains. The Ames crater, a 10-mile-wide impact structure buried beneath northwest Oklahoma, is about 100 million years younger than previously estimated, according to a new analysis of zircon crystals. Researchers found that the crater formed around 370 million years ago, during the Frasnian-Famennian mass extinction—one of Earth's major biodiversity crises. This revised age places the impact at a time when marine life was undergoing severe stress, raising questions about a possible link between the asteroid strike and the extinction event.
The study, which used advanced dating techniques on microscopic minerals, helps refine the timeline of both the crater and the extinction. Understanding the age and effects of such impacts can inform our knowledge of Earth's geological history and the forces that have shaped life on the planet.
