What Rock Layers Are Fossils Found In? Therefore, fossils are found in sedimentary rock, like sandstone, shale, limestone and coal. Igneous rock, like granite and basalt, is formed by molten rock erupting from deep within the earth. Metamorphic rock, such as marble, is formed by tremendous heat and pressure. What layer do you find fossils?
What Rock Is Fossils Usually Found In? Most fossils “hide out” in sedimentary rock .
