About 65 million years ago, according to a theory, one asteroid more than 6 to 7 miles across struck the coast of Mexico’s Yucatan Peninsula. The impact created the Chicxulub crater, more than 110 miles wide, and caused a gigantic dust cloud. The dust settled, forming the layer of an indium rich clay which is now found in sedimentary rock under the Atlantic and Pacific Oceans and in most northern landmasses. The cloud likely caused the world temperatures to drop linking this global cooling to the extinction of dinosaurs.
