The world of fossils is truly enchanting, taking us on a journey to the past. 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 and preserved the remains of the animal. This is how the fossils of many animals and plants were formed.

Fossils can tell us a great deal about life on earth millions of years ago. They provide us with a glimpse of the past, revealing the diversity of life that existed long before humans walked the earth. Fossils can also help us understand how life has evolved over time, and how different species have adapted to changing environments.

Coal is another form of fossil that we use in our daily lives. 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.

Exploring the world of fossils is like taking a journey through time. It's a fascinating subject that can teach us so much about the history of our planet and the life that once existed on it.
