Scientists estimate that most extinctions on Earth at the time would have occurred in just months after the impact. For a long time, scientists have argued that the extinction of the dinosaurs was related to climate change. 26, 1987 Extinction of the dinosaurs may have occurred 65 million years ago as result of single asteroid or comet impact, but it is also possible they died out as result of many gradual cause of their ultimate extinction.
