Limestone. However most large masses of limestone formed from coral reefs, not shells. The shell fossils in this limestone are "incidentals" due to shell dwelling organisms living on the periphery of the reef, not the bulk of the limestone.
Limestone is a common sedimentary rock formed from the accumulation of shell fragments, coral, and other marine organisms. Over time, these organic materials can become compressed and cemented together to create a solid rock formation.
A rock formed from deposits of shell fragment is Limestone.
Claystone, and shale are sedimentary rocks formed from lithified deposits of clay.
Sedimentary rock is the rock formed as a result of deposits from weathering and erosion. Sedimentary rock can be millions of years old.

A sedimentary rock formed from sand deposits is called sandstone. Sandstone is composed of grains of sand that are cemented together by minerals, creating a rock that is often used as a building material due to its durability and ease of cutting.
Limestone is a rock formed from the accumulation of calcium carbonate derived from the remains of sea shells and marine organisms. Over time, these sedimentary deposits can become compressed and cemented to form solid rock.
A rock formed for sedimentary deposits is called a sedimentary rock. A sedimentary rock which has then undergone metamorphism is called a meta-sediment.
Sedimentary rock, such as sandstone or shale, is often formed from soil deposits carried by moving water from rivers or streams. These sediments accumulate, compress, and cement over time to form rock layers.
