The event marks the end of the Mesozoic Era and the beginning of the Cenozoic Era. [12] "Tertiary" being no longer recognized as a formal time or rock unit by the International Commission on Stratigraphy, the K-T event is now called the Cretaceous—Paleogene (or K-Pg) extinction event by many researchers.
The K–Pg boundary marks the end of the Cretaceous Period, the last period of the Mesozoic Era, and marks the beginning of the Paleogene Period, the first period of the Cenozoic Era. Its age is usually estimated at 66 million years, [2] with radiometric dating yielding a more precise age of 66.043 ± 0.043 Ma. [3]
Craters were also formed near the K–Pg boundary, the largest the Mexican Chicxulub crater whose impact was a major precipitator of the K–Pg extinction, [44] and also the Ukrainian Boltysh crater, dated to 65.4 mya [45] the Canadian Eagle Butte crater (though it may be younger), [46] the Vista Alegre crater [47] (though this may date to ...

It is now widely accepted that the devastation and climate disruption resulting from the impact was the primary cause of the Cretaceous–Paleogene extinction event , a mass extinction of 75% of plant and animal species on ...
