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

The impact would have caused a megatsunami over tall that would have reached all the way to what are now Texas and Florida. The height of the tsunami was limited by the relatively shallow sea in the area of the impact; in deep ocean it would have been tall. A cloud of super-heated dust, ash and steam would have spread from the crater as the impactor burrowed underground in less than a
