They are all sediments.
The remains of living organisms are compressed and stuck together to form sedimentary rock, specifically a type called fossiliferous limestone. This rock is composed primarily of calcite and often contains fossils of marine organisms. Over time, layers of sediment accumulate, and the pressure from overlying materials causes the organic remains to lithify into solid rock.
A fossil. Fossils are the remains or traces of once-living organisms preserved in sedimentary rock.
A rock made from animal remains is called a fossiliferous rock. These rocks contain fossils, which are the preserved remains or traces of ancient organisms. Common examples include limestone and shale, where the remains of marine animals or plants are often found. Fossiliferous rocks provide valuable insights into the history of life on Earth.
Organic sedimentary rock is comprised of the remains of once living organisms.
The remains in question are the shells, as a source of calcium carbonate derived originally by the animal from solution in the sea-water..

The loose material is called sediment. It may include bits of rock, minerals, and organic material like plant and animal remains. This sediment can accumulate in layers over time and eventually become sedimentary rock through processes like lithification.

Sedimentary rock is formed when particles and bits of rock are cemented together through processes like compaction and cementation. This type of rock typically forms at or near the Earth's surface through the accumulation and solidification of sediments.
Fossils. Fossils are the preserved remains or traces of organisms found in rocks or other geological formations. They provide valuable information about past life forms and environments.
Sedimentary rock, specifically organic-rich sedimentary rock, can contain bits of soil and the remains of once-living things like plant and animal remains. Examples include shale, coal, and limestone formed from the accumulation and compaction of these materials over time.
