↓ More info and sources below ↓

Most people are taught that dinosaurs went extinct 66 million years ago when a giant meteor crashed into the Yucatan peninsula. I’m here to tell you that’s wrong. Dinosaurs are alive and well today, and you don’t have to go to Jurassic World to see them (although hanging out with Chris Pratt would be cool).

We have living dinosaurs all around us. We just call them “birds”.
