Fossils are the remains of plants and animals that lived millions of years ago and have since turned to stone. When an animal died, its body sank to the bottom of the water and gradually layers of sand or silt were deposited over it. Over thousands of years, the silt turned to stone, preserving the remains of the animal. This process formed the fossils of many animals and plants, which can tell us a great deal about life on earth many millions of years ago.

Fossils are not only found in the form of bones or shells but also in coal. Millions of years ago, whole forests sank down, were covered, and slowly petrified. These ancient tree trunks are now coal. Among the coal that is found in coal mines, there are often numerous animal fossils as well.

Fossils are a fascinating way to learn about the past. They provide us with a glimpse into the world as it was millions of years ago. By studying fossils, we can learn about the evolution of life on earth, the climate, and the geography of different regions.

So, if you're interested in history, science, or just curious about the world around you, take a trip through time with fossils. You never know what you might discover!
