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.

Toms Canyon impact crater USGS scientists, show that the crater was formed by an object or objects which struck from the southwest at a glancing angle and formed a long, oval crater. Since impact, sediment filled part of the crater, giving it its present triangular shape. Toms Canyon impact crater The Toms Canyon impact crater is a probable impact crater where one or more asteroids struck the Atlantic continental shelf, about east of Atlantic City, New Jersey.
