Fossil discovery refers to the process of finding preserved remains or traces of ancient organisms, such as plants and animals. These remains can include bones, teeth, shells, and even footprints. Fossils provide valuable information about the history of life on Earth, helping scientists understand how species evolved and how environments changed over time. Fossils are typically found in sedimentary rocks, where layers of mud and sand have compacted over millions of years. Notable fossil discoveries, like those of dinosaurs or early mammals, have significantly advanced our knowledge of prehistoric life and the planet's geological history.
