Limestone fossils

Limestone is a type of rock that is made up of bits of animal shells. Over millions of years these shells collected on the ocean floor. As layers of shells and mud built up, the lower layers slowly hardened into limestone.

fossils (e.g. fossiliferous limestone) ooliths; pellets; In contrast, the chemically-precipitated limestones consist solely of crystalline carbonates (e.g. microcrystalline limestone). The clastic limestones can be further subdivided according to their grainsize, much like other clastic sedimentary rocks. Other chemical sedimentary rocksThe fossils are usually mollusk or gastropod shells and shell fragments.
