The extiction
by: Jye J., Grade: 6+


It was about 65 million years ago when an asteriod 8-16 kilometers wide collided with the earth making a hugh crater which destroid anything in it's path. This crater killed alot of dinosaurs. Also the astriod sent billions of tonnes of dust and ash into the air. Which blocked out the sun for years and years, leaving the earth in darkness. due to the sun being blocked out many plants died leaving the herbivours with nothing to eat, they died. Because all the herbivours were dieing the carnivours had nothing to eat and were also killed. Many of the smaller dinosaurs survived by eating seeds, nuts and rotting plants. Once the dust clouds strated thinnig out the sun came through and many plants strated growing again and the surviving animals were no longer competing with each other for food because this was now the begining of the age of the mammals.
