Marine Fossils

Marine fossils are the preserved remains, shells, or imprints of ocean-dwelling organisms, such as fish, mollusks, corals, and other sea creatures, found within sedimentary rocks. They form when a living organism dies and is quickly buried by sediment, which then hardens over time into rock. These fossils provide valuable insights into Earth's ancient marine environments, climate changes, and the evolution of life. Studying marine fossils helps scientists understand the history of oceans and how marine ecosystems have changed over millions of years.
