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.
A sedimentary rock formed from deposits of shells is called limestone. Limestone is made up primarily of calcium carbonate, which is derived from the shells of marine organisms like coral or shellfish.
Limestone is created in small warm still waters where shells and other sediments create layer which in time turn into Limestone.
