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
Burckle Crater Burckle Crater Burckle Crater is an undersea feature hypothesized to be an impact crater by the Holocene Impact Working Group. They considered that it likely was formed by a very-large-scale and relatively recent (c. 3000–2800 BCE) comet or meteorite impact event. It is estimated to be about 30 km (18 mi) in diameter, about 25 times wider than Arizona's Meteor Crater. It is east of Madagascar and west of Western Australia in the southern Indian ocean adjacent to the SW Indian Ocean Ridge. Its position was determined in 2006 by the same group using evidence of its existence from prehistoric
