Timeline of Cretaceous–Paleogene extinction event research Hildebrand and William Boynton reported the Chicxulub crater in the Yucatan peninsula of Mexico as a probable impact site. While the controversy continued, the accumulating evidence gradually began to sway the scientific community toward the Alvarez hypothesis. In 2010, an international panel of researchers concluded that impact best explained the extinction event and that Chicxulub was indeed the resulting crater. Because the estimated date of the object's impact and the Cretaceous–Paleogene boundary (K–Pg boundary) coincide, there is now a scientific consensus that this impact was the Cretaceous–Paleogene extinction event which caused the death of most of the planet's non-avian dinosaurs
Toms Canyon impact crater 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. The submarine canyon is the drowned glacial-age mouth of Toms River. The crater dates to the late Eocene geological time period (about 35 million years ago), and may have been formed by the same event as the larger Chesapeake Bay impact crater (and possibly the Popigai crater in Siberia), to the southwest at the mouth of Chesapeake Bay, also dating to the late Eocene.
