Shale
Coquina is a sedimentary rock fitting that description.

Shale Rock
Organic Sedimentary rock would probably be the best answer!
Yes, coral reefs are made of the limestone skeletons of deceased corals - the living corals are on the surface of the reef.
Limestone and chalk.
No, shale is a type of sedimentary rock formed from the accumulation of silt and clay particles. It is not formed from the skeletons of ancient coral animals, which are typically preserved in rocks such as limestone.
Yes, sedimentary rocks often contain shells and skeletons of marine animals, including corals. These fossils are typically found in limestone and other sedimentary formations that have formed from the accumulation of organic material and sediments in aquatic environments. Over time, the remains of these organisms become embedded in the rock as it undergoes lithification. Thus, sedimentary rocks can provide valuable insights into past marine ecosystems.
A rock formed from crushed shells and coral is known as coquina. Coquina is a sedimentary rock that is composed of fragmented shell and coral debris cemented together. It is commonly found along coastlines and can have a characteristic porous appearance.
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 a rock that is formed from the skeletal remains of sea animals and plants. It is primarily composed of calcium carbonate, which is derived from the shells and skeletons of marine organisms such as coral, mollusks, and foraminifera. Over time, these remains accumulate and become compacted and cemented to form limestone rock.
coral reefs were formed by the calcium of skeletons
