Apr 23, 2018 · The Rock Most Likely to Contain Fossils. Fossils, the preserved remains of animal and plant life, are mostly found embedded in sedimentary rocks. Of the sedimentary rocks, most fossils occur in shale, limestone and sandstone. Earth contains three types of rocks: metamorphic, igneous and sedimentary. Igneous rocks, which form from cooling magma or lava, and metamorphic rocks, which have been altered by heat and pressure, are unlikely to contain fossils (but may, under special circumstances). Since rapid burial in sediment is important for the formation of fossils, most fossils form in marine environments, where sediments are more likely to ...
