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
Obolon' crater that Obolon' may have been part of a hypothetical multiple impact event which also formed the Manicouagan crater in northern Quebec, Rochechouart crater in France, Saint Martin crater in Manitoba, and Red Wing crater in North Dakota. All of the craters had previously been known and studied, but their paleoalignment had never before been demonstrated. Rowley has said that the likelihood that these craters could be aligned like this due to chance is nearly zero. Obolon' crater Obolon' crater is a diameter buried meteorite impact crater situated about southeast of Kiev in Ukraine (Poltava Oblast). The site has been drilled,
