How did the dinosaurs become extinct?

There are many factors that caused the extinction of dinosaurs, and the scientific community has not yet reached a conclusion.

But the most fundamental reason is that the dinosaurs could not adapt to the environment or climate changes at that time, so they perished.

The extinction of the dinosaurs refers to the mass extinction event of the Cretaceous period at the end of the Mesozoic Era that occurred about 650,000 years ago. It is a diversified dominant vertebrate in the Mesozoic Era and has dominated the global terrestrial ecosystem for more than 1.6 billion years.
