Some sedimentary rocks are formed at least partially of the remains of living things, but many are not. Fossil-rich rocks, coal, and some types of limestone are composed partly of the remains of organisms. Clastic sedimentary rocks such as shale and sandstone are made from sediment that has weathered out of pre-existing rock.
It depends on the origin and location (where they come from or was generated) of the parent materials, particles and sediments.

fossils
These small particles are known as clasts. If they are the remains of living things they may be known as bioclasts. The remains of animals are called fossils if they have hardened and become preserved.
All fossils are found in sedimentary rocks. Some sedimentary rocks are made of nothing but fossils such as chalk. A creature ( microscopic or larger) skeleton is deposited after death usually on the ocean floor. Sediments cover it, and over time turns into a fossil.
Sedimentary rocks.
Organic sedimentary rocks like coal and some limestones, are composed of particles created by life processes. In the case of coal it is plant remains. With limestones, it is the shells and secretions of small marine organisms.
Dont use wiki its dumb
Biosedimentary rocks (i.e. Biologically formed sedimentary rocks). Eg Coal.
These remains are called fossils.
They are referred to as clasts or bio-clasts.
yes they are

Organic Sedimentary Rocks are formed from remains of plants and animals.
It is true that the composition of a sedimentary rock depends upon the composition of the rocks and living things its sediments come from. Sedimentary rocks form through lithification.
There are different ways sedimentary rocks are formed. Many sedimentary rocks are made from the broken pieces and particles of other rocks, [which is a reason why the name was given to these types of rocks (sediment)] and these bits get cemented together. These types of sedimentary rocks are called clastic sedimentary rocks. Chemical sedimentary rocks are another type that comprise of mineral crystals, like gypsum and halite. Lastly, organic sedimentary rocks are made of, well...... organic materials. They are made of the remains of once living organisms and contain the remains of living creatures such as clam shells, plankton skeletons, dinosaur bones, and plants.
