The Mammoth Steppe

Chapter I

The Mammoth Steppe

Ice Age · about 20,000 years ago

Cold wind, endless grass and the low rumble of a herd on the move. Our own ancestors walked here and painted these animals on cave walls.

  • Woolly mammoths survived on Wrangel Island until about 4,000 years ago
  • Smilodon’s sabers reached about 18 cm
  • Frozen carcasses still preserve mammoth hair
Hell Creek, Montana

Chapter II

Hell Creek, Montana

Late Cretaceous · 68–66 million years ago

The last great age of the dinosaurs. Warm rivers, flowering trees, and a tyrant with lips over its teeth — not the snarling movie version.

  • T. rex had two working fingers on each hand
  • There was no grass yet — only ferns and flowering plants
  • Triceratops horns changed direction as it grew
Gobi desert dunes at dawn, 73 million years ago

Chapter III

The Gobi Dunes

Late Cretaceous · 75–71 million years ago

A turkey-sized hunter crosses the sand at dawn. Forget the movies: this is what the fossils say.

  • Scaly skin, no feathers
  • Taller than a person
  • Hunts in clever packs, opens doors

The Morrison Floodplain

Chapter IV

The Morrison Floodplain

Late Jurassic · 155–145 million years ago

Blue hour on a river plain in what is now Colorado. Long necks rise above the conifers, and Stegosaurus browses low among the ferns.

  • No flowers had evolved yet
  • T. rex lived closer in time to us than to Stegosaurus
  • Allosaurus was the most common large predator here
