Dinosaur extinction. Artwork of a Tyrannosaurus rex dinosaur with falling meteorites. The impact of a large meteorite occurred about 65 million years ago at the end of the Cretaceous geological period. The impact was at least partly responsible for the extinction of a wide range of creatures,including the dinosaurs. Estimated to be about 20 km's across,the meteorite struck the Earth in the area now known as the Yucatan peninsula in Central America. It threw vast amounts of debris into the upper atmosphere. The debris blocked out the sunlight causing darkness and lowering global temperatures. The remains of this debris is found as a layer in rocks called the 'K/T boundary' | |
