T. Rex and the Crater of Doom the Brazos river that a tsunami has swept across the Gulf of Mexico millions of years earlier. The discovery was made thanks to a graduate student named Alan Hildebrand that notified Alvarez of the evidence of a crater on the Yucatan peninsula, which had never been published in the scientific literature by the Mexican petroleum geologists that had found it. The age of the crater needed to be determined if it was going to be a candidate for the KT boundary impact, but access to the region was limited by the crater being buried over time and the core samples
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.
