Boltysh crater Boltysh crater The Boltysh Crater (Bovtyshka Crater) is an impact crater in the Kirovohrad Oblast of Ukraine, near the village of Bovtyshka. The crater is in diameter and its age of 65.17 ± 0.64 million years, based on argon dating techniques, is within error of that of Chicxulub Crater in Mexico, and the Cretaceous–Paleogene boundary (K–Pg boundary). The Chicxulub impact is believed to have caused the mass extinction at the end of the Cretaceous period, which included the extinction of the dinosaurs. The Boltysh impact likely occurred several thousand years before Chicxulub, suggesting the extinction event may have been driven
Pingualuit crater dating back to the last interglacial period 120,000 years ago. Preliminary results show that the upper 8.5 m sediment core contains records of two interglacial periods. Pingualuit crater The Pingualuit Crater (; from Inuit "pimple"), formerly called the Chubb Crater and later the New Quebec Crater (), is a young impact crater, by geological standards, located on the Ungava Peninsula, in the administrative region of Nord-du-Québec, in Quebec, Canada. It is in diameter, and is estimated to be 1.4 ± 0.1 million years old (Pleistocene). The crater and the surrounding area are now part of Pingualuit National Park. The only
