Organic sedimentary rock is comprised of the remains of once living organisms.
Sedimentary rock can be made from sediments cemented together, or formed in the shape of remains of living things. Igneous rock is made from cooled magma, inside or outside the crust.
Many rocks can contain fossil organisms. Generally speaking, sedimentary rocks are the rock type that contains the most fossil organisms. Coquina, a type of limestone, is formed nearly completely by the shells of marine organisms. And coal is a sedimentary rock composed of the remains of ancient swamp plants.
Clastic sedimentary rocks, like conglomerate and sandstone.
They are called organic sedimentary rocks, such as coal and chalk.
The only rock that can form in this way is limestone formed from calcium carbonate concentrated in shells and exoskeletons like corals. The rock itself comes from sediment rich in these materials after the animals' deaths.

Sedimentary rock can be made from sediments cemented together, or formed in the shape of remains of living things. Igneous rock is made from cooled magma, inside or outside the crust.
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.
Organic sedimentary rocks are formed from the accumulation of once living things. Coal is an example of a sedimentary rock.
Coal.
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.
nonclastic
it is to be called inorganic
sedimentary rock
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.
fossil
Because the fossils cannot survive the intense heat.
