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. Chicxulub crater The Chicxulub crater (; ) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is located near the town of Chicxulub, after which the crater is named.

Burckle Crater Burckle Crater Burckle Crater is an undersea feature hypothesized to be an impact crater by the Holocene Impact Working Group. They considered that it likely was formed by a very-large-scale and relatively recent (c. 3000–2800 BCE) comet or meteorite impact event. It is estimated to be about 30 km (18 mi) in diameter, about 25 times wider than Arizona's Meteor Crater. It is east of Madagascar and west of Western Australia in the southern Indian ocean adjacent to the SW Indian Ocean Ridge. Its position was determined in 2006 by the same group using evidence of its existence from prehistoric
