Fossil limestone rock.

Oolite or oölite (from Ancient Greek ᾠόν (ōión) 'egg stone') [1] is a sedimentary rock formed from ooids, spherical grains composed of concentric layers.

Limestone is a carbonate sedimentary rock that consists predominantly of calcite [CaCO 3].Limestones are the commonest rocks that contain non-silicate minerals as primary components and, even if they represent only a fraction of all sedimentary rocks (about 20 – 25%), their study is fundamental to understand past environments, climate, and the evolution of life.

Ammonite fossils are the preserved remains of ammonoids, which were marine creatures with a spiral shell that resembled a ram’s horn. These fossils are often found in sedimentary rocks, such as limestone and shale, and can provide valuable insights into the evolution and ecology of ancient marine life.

Marble is a metamorphic rock formed by the alteration of limestone by heat and pressure. The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. If the limestone is pure, a white marble is formed.Named for Bethany, Missouri, this particular limestone is dotted around the city, a rock shelf about 15-30 feet thick that extends for hundreds of miles, shaping the landscape and ecology.The dead living creatures termed fossils hence rock consist of fossils known as Fossiliferous Limestone.

Calcium carbonate is also the dominant consituent of the rock, limestone. Because modern corals live in large colonies, these skeletons can become quite large, sometimes forming reefs. When the polyp dies, its soft tissue decays, but the hard skeleton is left behind. The hard skeleton of ancient corals is what is preserved as a fossil.

The crystals grow larger with time and become recognizable as interlocking calcite crystals. This recrystallization process stops fossil and sedimentary structures of the limestone. Recrystallization also differentiates marble and limestone.
