LaoThe mass extinction event that killed the dinosaurs is believed to have been caused by a large asteroid impact that occurred around 66 million years ago. This impact resulted in a catastrophic chain of events, including widespread wildfires, tsunamis, and a nuclear winter-like effect caused by dust blocking out sunlight, leading to the extinction of the dinosaurs and many other species.

Some scientists believe that dinosaurs became extinct when a comet crashed into Earth. This catastrophic event led to widespread environmental changes, including extreme climate conditions that likely contributed to the mass extinction of dinosaurs and many other species.
Did the dinosaurs extinct at once?
No, dinosaurs did not go extinct all at once. The extinction event that wiped out the non-avian dinosaurs around 66 million years ago is believed to have happened relatively quickly in geologic terms, but not instantaneously. Some species may have gone extinct earlier or later than others due to various factors.
Do dinasours exsits?
No, dinosaurs are extinct and have been for millions of years. The last dinosaurs lived during the Late Cretaceous period, around 65 million years ago, before they were wiped out by a mass extinction event.
When did the first dinosaurs appeared on earth?
The first dinosaurs appeared on earth about 250 million years ago just after the Permian-Triassic mass extinction. The Triassic dinosaurs weren't too fierce and they were mainly neutrally defensive, which means they don't attack unless provoked.
