Fossiilikerroksia

Fossiilikerroksia, or fossiliferous rocks, are sedimentary rocks that contain fossils, which are the preserved remains or traces of ancient organisms. These rocks are crucial for paleontology, as they provide evidence of past life and help scientists understand the history of life on Earth. Fossiliferous rocks can be found in various geological settings, including marine, terrestrial, and freshwater environments. They are typically composed of sediment that accumulates over time, trapping and preserving fossils within their layers. The types of fossils found in these rocks can vary widely, from the shells of marine organisms to the bones of land animals and even the imprints of plants. The study of fossiliferous rocks helps scientists reconstruct ancient ecosystems, track the evolution of species, and understand the geological processes that have shaped the Earth's surface over millions of years. These rocks are often found in outcrops and quarries, where they can be exposed to the surface and studied by geologists and paleontologists.
