Something to ponder.....

The length of time between the existence of the Stegosaurus and the Tyrannosaurus rex is longer than the length of time between between the existence of the Tyrannosaurus rex and yourself.

Stegosaurus

Late Jurassic
155-150 million years ago

...approx. 80 million years go by...

Tyrannosaurus rex

Late Cretaceous
70-65 million years ago

...approx. 65 million years go by...

Homo sapiens (us)
