The Paleogene

The Paleogene was a very old time in Earth's story. It started about 66 million years ago and lasted until 23 million years ago. This was a special time right after the dinosaurs were gone. Many new animals, especially mammals, began to grow and change.

During the Paleogene, the world looked very different. The continents moved apart, and new oceans formed. Big mountains like the Alps and Himalayas began to rise. The weather also changed a lot. It was very warm at first, then cooled down, and ice started to form in Antarctica.

Animals and plants changed quickly during this time. Mammals grew bigger and learned to live in many places, like forests, oceans, and even the air. Birds became very common and flew everywhere. Plants also changed, with new types growing in different climates.

The Paleogene helped shape the world we live in today. It was a time of big changes for Earth, its lands, and the living things that called it home.
