Chicxulub crater of the resulting megatsunami represented in a New Jersey quarry, a dense marine bone bed was found on the Cretaceous–Paleogene boundary containing a mixture of dead sea animals with little or no damage from scavengers or predators. Also related to this tsunami was a dense dinosaur bone bed on the Cretaceous–Paleogene boundary found in Patagonia.

Pingualuit crater dating back to the last interglacial period 120,000 years ago. Preliminary results show that the upper 8.5 m sediment core contains records of two interglacial periods. Pingualuit crater The Pingualuit Crater (; from Inuit "pimple"), formerly called the Chubb Crater and later the New Quebec Crater (), is a young impact crater, by geological standards, located on the Ungava Peninsula, in the administrative region of Nord-du-Québec, in Quebec, Canada. It is in diameter, and is estimated to be 1.4 ± 0.1 million years old (Pleistocene). The crater and the surrounding area are now part of Pingualuit National Park. The only
