fossil remains

Fossil remains are the preserved remains or traces of ancient organisms found in sedimentary rocks. They can include bones, teeth, shells, and even the footprints of animals. Fossils provide crucial information about the history of life on Earth, showing how species evolved and how ecosystems changed over millions of years. They form when organisms are buried by sediment, which protects them from decay, eventually turning into rock. Scientists study fossils to learn about past environments, climate changes, and the organisms that lived long ago, helping us understand the Earth's biological history.
