Browsing: Fossils

Fossils are the preserved remains or traces of ancient organisms, typically embedded in sedimentary rock formations. These remnants can include bones, shells, leaves, and even traces of microbial activity, which over millions of years have transformed into stone through processes such as mineralization, where minerals gradually replace the organic material. Fossils play a critical role in paleontology, the scientific study of life in the geological past, providing valuable insights into the evolution and diversity of life on Earth. They help scientists understand extinct species, reconstruct past ecosystems, and trace the evolutionary history of current species. The fossil record, although incomplete, acts as a historical timeline, offering evidence about the different organisms that existed at various periods and their interactions with the environment. This information is crucial for understanding biological and geological processes and for tracking the effects of climatic and environmental changes over Earth’s history.
