Sandstone is made from grains of sand that have melded together over time, or lithified. Sedimentary rock often contains fossils of plants and animals millions of years old. The mudstone cliffs along the southern coast of England have many fossils from the time of the dinosaurs. Some examples of sedimentary rocks. Chalk is a fine-grained limestone, usually formed by compacted microscopic animals called foraminifera. Chert is a fine-grained hard sedimentary rock composed of microscopic silica grains, and has a flat fracture. Flint is a variety of chert (mostly of upper Cretaceous age) that has a conchoidal fracture. Sedimentary rocks are derived from pre‑existing rocks by weathering and erosion. The resulting particles settle out of water or air (clastic rocks such as sandstone and mudstone) or the resulting chemicals precipitate from concentrated solutions (non‑clastic rocks such as limestone and salt).
