Limestones are sedimentary rocks made of skeletal remains. Limestones are recognizable because they react with Acid.
Crystalline limestone are micro skeletons with large visible crystals.
Micritic limestone is lithographic limestone and it is basically fine grained mud with micro-skeletons.
Fossiliferous limestone is made with whole fossils in my experience mostly shells.
Coquina is parts of skeletons pressed together. The difference between coquina and fossiliferous is that coquina doesn't have whole fossils.
Lastly there is chalk. This is a lot of microorganisms remains pressed together.

What are the remains of once-living orgainismsfound in sedimentary rocks?
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.
Do sedimentary rocks form from the remains of living things?
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.
Are sedimentary rocks made up of?
Sediment, compressed dead solid organisms.
What are sedimentary rocks made up of?
Sediment, compressed dead solid organisms.
Can Plant and animals form sedimentary rock?
Skeletal remains of many sea creatures settle on the ocean floor. Here they mix with sediments and eventually become sedimentary rock.
Sedimentary rock made up of the remains of living things?
Organic sedimentary rock is comprised of the remains of once living organisms.
What kind of sedimentary rock is made from the remains of organisms or fossils?
Clastic sedimentary rocks, like conglomerate and sandstone.
A rock formed from living organisms?
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.
Is limestone made up of fragments of granitic and andesitic rocks?
No. Limestone is formed from precipitated calcite or from the shells or skeletal remains of marine organisms.
Where is limestone made?
Like most other sedimentary rocks, limestone is composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera.
What is the huge mass of limestone made of?
Limestone is composed of the skeletal remains of minute sea creatures. The layers are then subjected to compression and, over a very long time, hardened into a sedimentary rock.
What rock is made by the planets remains?
sedimentary rock

What type of sedimentary rock is made from dead organisms?
Limestone.
How are sedimentary rocks mader?
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.
