The fossil record is the totality of fossilized remains found in sedimentary rocks around the world, providing a chronological record of past life on Earth. It offers key evidence for the study of evolution, paleoenvironments, and the history of biodiversity. The fossil record is crucial in paleontology and helps to document the rise and fall of species over geological time.
