Charlie Paull and colleagues from the Monterey Bay Aquarium Research Institute presented the first undersea mapping of the impact crater that is thought to be responsible for the death of most of the dinosaurs on Earth about 65 million years ago at the Dec. 9, 2013, session of the annual meeting of the American Geophysical Union in San Francisco, California.
The researchers focused their efforts on the Campeche Escarpment. The Campeche Escarpment is an underwater mountain that extends for 360 miles north of the Yucatan Peninsula in Mexico. The mountains are 12,800 feet high and form the northernmost boundary of the meteorite impact crater that is considered to be the only remnant of what caused the extinction of most dinosaurs around 65 million years ago.
The detailed mapping shows a variety of layers of sedimentary rock. The researchers propose that the Campeche Escarpment contains records of life before, during, and after the extinction event that occurred 65 million years ago.
Future research plans include making a complete analysis of each layer of the Campeche Escarpment using core samples. This research may lead to the discovery of the exact nature of the stellar body that was responsible for killing most of the world’s dinosaurs.
Detailed images of the discovery can be seen at Google Earth.
