Biosedimentary rocks (i.e. Biologically formed sedimentary rocks). Eg Coal.
Biogenic sedimentary rocks form from remains of living things.Also, limestone rock may contain things that once lived.
Organic sedimentary rocks.
something that starts with an "o"
Organic rocks
lime stone
Organic Sedimentary Rocks are formed from remains of plants and animals.
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.
shells, bones and fossils

Chemically formed sedimentary rocks are formed from dead remains of plants and animals that is from an organic sediment.
weathered remains of other rocks
limestone is formed
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.
Sedimentary.
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 remains of plant and animal life. Chemical sedimentary rocks are formed from the precipitation of minerals in a solution.
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.
