The World 100 Million Years Ago

Imagine standing on Earth 100 million years ago. The world was almost unrecognizable. There were no humans, no cities, no continents shaped the way we see them now. The air was thicker, the temperature much warmer, and the planet was alive with creatures so large and strange that today they feel almost mythical.

During this time — known as the Cretaceous Period — dinosaurs ruled every corner of the planet. Towering trees covered vast jungles, and giant ferns grew beside volcanic plains. The continents were still slowly drifting apart, forming the shapes of North America, Africa, and Asia as we know them today.

The oceans were teeming with life. Massive reptiles like Mosasaurus and Plesiosaurus hunted beneath the waves, while strange fish and ammonites drifted near the surface. The sea level was so high that much of the land we know now was underwater. If you stood where Kansas is today, you might have been swimming with ancient sea monsters.

On land, Tyrannosaurus rex was not yet the king — but other massive predators, like Giganotosaurus and Spinosaurus, stalked the forests. Herds of duck-billed dinosaurs wandered the plains, while flying reptiles — Pteranodons with wingspans wider than a car — soared above.

Plants were evolving too. This was the era when flowers first appeared. Before that, the world was green but not colorful. Once flowers emerged, the planet began to bloom — literally. This change would forever alter the course of life on Earth, giving rise to new species of insects and animals that depended on nectar and pollen.

The climate was warm and humid, even near the poles. Antarctica was covered not in ice, but in forests filled with ferns and conifer trees. Dinosaurs roamed there too, adapted to months of light and darkness.

Then, about 66 million years ago, everything changed. A massive asteroid — over six miles wide — struck Earth near what is now the Yucatán Peninsula in Mexico. The explosion was millions of times more powerful than any human-made bomb. It caused massive wildfires, earthquakes, and a global winter that blocked sunlight for years.

Most dinosaurs didn’t survive this catastrophe. But not everything died. Small mammals — tiny, shrew-like creatures — managed to survive underground. From them, millions of years later, came primates… and eventually, us.

So, the next time you look up at the stars or walk through a forest, remember — this world has seen ages of change, giants walking, and entire species rising and vanishing. The Earth you stand on today is the result of a billion years of creation, destruction, and rebirth.
