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
Tunnunik impact crater Tunnunik impact crater The Tunnunik impact crater, formerly known as the "Prince Albert Impact Crater", is a recently confirmed meteorite impact crater. It is located on Prince Albert Peninsula in the northwestern part of Victoria Island in Canada's Northwest Territories. The wide crater was discovered in 2010 by Brian Pratt, professor of geology at the University of Saskatchewan, and Keith Dewing of the Geological Survey of Canada during an aerial survey of the region. The crater is estimated to have formed between 130 and 350 million years ago, and may have been created when a meteor a few kilometres in
