No, shells are biomaterial, not rocks.
shells
carbonaceous shells form limestone which in this case is a bio-chemical sedimentary rock
An organic sedimentary rock composed of cemented shells is called limestone. Limestone is primarily made up of the mineral calcite, which is derived from the shells of marine organisms like coral and mollusks. Over time, these shells accumulate and compress to form solid rock.
An organic sedimentary rock made of microscopic shells is called limestone. Limestone is mainly composed of calcium carbonate derived from the accumulation of marine organism shells such as shells of foraminifera, coral, and mollusks. Over time, these shells compact and cement together to form solid rock.
yes
Limestone is a sedimentary rock formed by cemented shells of marine organisms such as corals and shellfish. The accumulation of these shells, along with other calcium carbonate materials, over time creates limestone rock.
When marine organisms die, their shells can eventually become limestone rock through a process called lithification. This process involves the compaction and cementation of the shells over time, creating a solid rock formation.
Limestone made from shells would be an organic sedimentary rock.

chalk
A sedimentary rock called coquina.
