Fossils are the remains of plants and animals that lived millions of years ago and have since turned to stone. These fossils can tell us a great deal about life on earth many millions of years ago. 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 a period of thousands of years, the silt turned to stone and so did the remains of the animal which were preserved in it. In this way, the fossils of many animals and plants were formed.

Fossils are a glimpse into the ancient world, and they can teach us a lot about the past. For example, we can learn about the types of animals and plants that existed millions of years ago, their habitats, and their behaviors. We can also learn about the climate and environment of the time.

There are even some fossils that we burn in our homes to keep warm. These are, of course, in the form of 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 fascinating and provide us with a unique window into the past. They remind us of the incredible diversity of life that has existed on our planet and how it has changed over time. By studying fossils, we can gain a better understanding of our world and our place in it.
