Special attention is given to a description of the boundary Chicxulub impact structure in Mexico, which forming became the final event of the Mesozoic aera and caused a mass biota extinction at the Cretaceous-Paleogene boundary. The impact structures of the Ukrainian Shield are described. The Boltysh impact crater is characterized in details that was formed at the Cretaceous-Paleogene boundary almost simultaneously with the Chicxulub crater. The Boltysh ejecta are the key horizon of the Cretaceous-Paleogene boundary of mass extinction in the central part of the Ukrainian Shield.
