Human - Tyrannosaurus rex - Stegosaurus
The age of dinosaurs was probably longer than you think. T-Rex lived at the end of the Cretaceous period, just before the dinosaur-killing asteroid strike 66 million years ago.
Stegosaurus, and other popular Jurassic dinosaurs such as Diplodocus, lived around 150 million years ago.
So, the T-Rex lived closer to the modern day than to the time of Stegosaurus. By the time T-Rex walked the Earth, Stegosaurus were already fossils beneath their feet.
