Dinosaurs were on the earth for millions and millions of years – from about 250 million years ago until 65 million years ago. They were found across the earth – living in deserts, forests, oceans, grassland, swamps. They survived all year round.
We still don’t know how old dinosaurs got…but increasingly, people are thinking that some dinosaurs lived until they were over 100!
All times of year! Like Claire said, dinosaurs were in all different environments, since Jurassic Park it’s hard to think of them in anything but a tropical jungle but in fact they survived just fine in cold weather too 🙂
