Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains. Dead organisms can become sediments which may, under the right conditions, become sedimentary rock.
Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in three main waysâby the deposition of the weathered remains of other rocks (known as clastic sedimentary rocks); by the deposition of the results of biogenic activity; and by precipitation from solution.ther examples include stromatolites, and the flint nodules found in chalk (which is itself a biogenic sedimentary rock, a form of limestone). Precipitate sedimentary rocks. Precipitate sedimentary rocks form when mineral solutions, such as sea water, evaporate.
