These remains are called fossils.
Organic sedimentary rocks, such as limestone and coal, are formed from the remains of once-living things. Limestone is primarily made of calcium carbonate from the shells and skeletal remains of marine organisms, while coal forms from the buildup of plant material in swampy environments over millions of years.
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, specifically organic-rich sedimentary rock, can contain bits of soil and the remains of once-living things like plant and animal remains. Examples include shale, coal, and limestone formed from the accumulation and compaction of these materials over time.
When sediments of living things are pressed together, they can form fossils. Over time, the pressure and minerals in the sediments can turn the organic material into rock, preserving the remains of the living organisms as fossils.
Well, isn't that just fascinating? Sedimentary rocks formed from the remains of dead organisms are called biogenic sedimentary rocks. Some common examples include limestone, formed from the accumulation of marine animal shells, and coal, which comes from the remains of ancient plants. Nature has a beautiful way of preserving life in the rocks around us.
Quartz is a mineral that is not formed from living organisms or their remains. It is typically formed through the crystallization of molten rock material or by precipitation from mineral-rich fluids.

The type of sedimentary rock formed from the remains of once-living things is called organic sedimentary rock. This includes rocks like limestone, which can form from the accumulation of shell, coral, and other biological materials. Another example is coal, which is formed from the compressed remains of plant material. These rocks provide important insights into past environments and biological activity.
