Impact event Chicxulub Crater. This crater is centered on the Yucatán Peninsula of Mexico and was discovered by Tony Camargo and Glen Pentfield while working as geophysicists for the Mexican oil company PEMEX. What they reported as a circular feature later turned out to be a crater estimated to be in diameter. This convinced the vast majority of scientists that this extinction resulted from a point event that is most probably an extraterrestrial impact and not from increased volcanism and climate change (which would spread its main effect over a much longer time period). Although there is now general agreement that there
Tunnunik impact crater diameter struck the Earth. The desert-like landscape of impact craters like Tunnunik can be useful in understanding the geology of other rocky planets such as Mars. It is Canada's 30th known meteorite impact feature. Not to be confused with the unconfirmed Victoria Island structure in California, United States. Tunnunik impact crater The Tunnunik impact crater, formerly known as the "Prince Albert Impact Crater", is a recently confirmed meteorite impact crater. It is located on Prince Albert Peninsula in the northwestern part of Victoria Island in Canada's Northwest Territories. The wide crater was discovered in 2010 by Brian Pratt, professor of
