- **155 million years ago – 145 million years ago** · Nature and deep time · **Stegosaurus lives in Late Jurassic North America**: Stegosaurus lived between about 155 and 145 million years ago. At least 76 million years separate the last Stegosaurus from the first Tyrannosaurus, more than the 66 to 69 million years that separate Tyrannosaurus from us.

- **69 million years ago – 66 million years ago** · Nature and deep time · **Tyrannosaurus rex lives in Late Cretaceous North America**: Tyrannosaurus lived about 69 to 66 million years ago. That puts it closer in time to us than to Stegosaurus, which had been extinct for at least 76 million years when the first Tyrannosaurus appeared.

The population stayed stable for about 6,000 years, so mammoths were still alive there while the Great Pyramid was being built.
