Dinosaurs lived on Earth for a whopping 165 million years. Then about 65 million years ago the Age of Dinosaurs came to a screeching halt when what scientists believe was an asteroid crashed into our planet. It left a crater 93 miles wide and 12 miles deep. This crater is called the Chicxulub (chik-shoo-loob) Crater which is buried underneath the Yucatan peninsula in Mexico.
Scientists believe as a consequence of this impact a huge dust cloud formed around the earth and blocked the sun’s light and energy. This in turn triggered a “Nuclear Winter” which made everything really cold really fast. Within weeks lakes and plant life froze leaving the dinosaurs hungry and cold. Eventually with no food or warmth, the dinosaurs went extinct.
