1.) Coal. Coal is generally formed from prehistoric plant material usually in a swamp environment The plants die and are buried in a low energy, low oxygen environment. The material then forms coal as a function of pressure, temperature and time.
2.) Coquina. Coquina is a general rock name for another type of sed rock that can be said to have been formed by living creatures. It is a rock almost completely comprised of broken up and weathered fossils of trilobites, mollusks, brachiopods and other invertebrates.
Sedimentary rock can be formed from lithified sediments.
Clastic sedimentary rock is sedimentary rock that is formed from rock particles.
Clastic sedimentary rocks: Formed from the accumulation of mineral and rock fragments that are cemented together. Chemical sedimentary rocks: Formed from precipitation of minerals dissolved in water. Organic sedimentary rocks: Formed from the accumulation of organic material, such as plants or animals.
Shale is a sedimentary rock formed from the compaction of fine-grained sediment such as mud or clay.
A sedimentary rock is formed when rock fragments are compacted and cemented together by pressure and minerals. Examples of sedimentary rocks include sandstone, shale, and conglomerate.
The only sedimentary rock type that can be formed from things once alive is organic sedimentary rock, specifically coal. Coal is formed from the accumulation and compaction of plant material, primarily in swampy environments, over millions of years. Other examples of organic sedimentary rocks include some types of limestone, which can form from the remains of marine organisms.
The only sedimentary rock type that can be formed from things that were once alive is organic sedimentary rock. It is primarily composed of the remains of plants and animals, such as shells, bones, and plant matter. These organic materials undergo compaction and cementation over time to form rocks like limestone and coal.
