IIt is called organic matter.
They are called fossils.
Living things that have been decayed
Fossils
Sedimentary rock.
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.
A rock formed from the remains of living things is called a sedimentary rock. This type of rock is formed through a process known as lithification, where sediments such as dead plants or animals accumulate and become compacted over time. Examples include limestone, coal, and chalk.
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.
Over time, any remains of living things in sediment may slowly harden and change into fossils trapped in the rock.
