Limestone is made out of remains of tiny shells and micro skeletons that are deposited on the sea bed. These include skeletal remains of aquatic organisms such as corals and sea snails. The pressure from the water, shells and sand compressed them together into the rock.

Limestone is made out of the shells of little tiny sea snails, minerals calcite and aragonite and crystal forms of calcium carbonate. Limestone is also made up of varying amounts of clay, silica, silt sand, diatoms and radiolarians.
Limestone is a type of sedimentary rock that is made from remains of micro skeletons and tiny shells, which are deposited on a sea bed. It reacts with dilute hydrochloric acid and it is composed of calcium carbonate. Limestone appears in layers referred to as bedding planes.
Limestone is an organic sedimentary rock that consists of calcium carbonate. Limestone is formed in layers known as bedding planes, which are a result of the remains of tiny shells and micro-skeletons deposited on the sea bed.
Limestone is a type of sedimentary rock composed of calcium carbonate. It is usually formed from the skeletons of marine organisms which accumulate over time. However, some limestone is formed totally by the chemical precipitation of minerals such as calcite or aragonite. When limestone rock dissolves in water and weak acidic solutions, karst landscapes are formed.
Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3).
Limestone is made from the precipitation of calcium carbonate. It is formed in a marine environment with the calcium having been brought to the sea through the hydrological cycle. Pure limestone is white but because of the impurities, it exhibits different colours.
Limestone is made of calcite or calcium carbonate. This mineral is usually formed under the water of oceans, lakes, or seas from organisms that live in the water. You can find more information here: http://www.otile.com/what-is-limestone.asp
