The four substances that help preserve the remains of organisms are amber, ice, tar, and sedimentary rock. Amber, a fossilized tree resin, can encapsulate and protect organisms, while ice can preserve remains in permafrost conditions. Tar, like that found in natural asphalt, can trap and protect bones and other materials, while sedimentary rock can encase and fossilize remains over geological time. Each of these substances creates an environment that limits decay and preserves the physical characteristics of the organisms.
Carbon, hydrogen, oxygen, and nitrogen are the four key elements that combine in various ways to form molecules in organisms. These elements are crucial for the structure and function of biological molecules such as carbohydrates, lipids, proteins, and nucleic acids.
Yes, a worm can be fossilized, but it is extremely rare, because it has no skeleton to be mineralized over time. So the only way you could find a fosssil of a worm is in a sandstone, because there it could have chances to be preserved.
Fossilized tree sap is called amber. It is formed when tree resin hardens and becomes buried in the ground, where it can undergo a process of polymerization over millions of years. Amber often contains prehistoric insects or other small organisms preserved within it.
THEY ARE SORTED BY SIZE
fossilized shell
A biostrome is a horizontally-bedded stratum of fossilized remains of sedentary organisms.
Fossil evidence can be interpreted in a multitude of ways. The posture and walking speed of a dead animal can be deduced from a fossilized set of footsteps while fossilized bones and scales can give insight to the animal's internal structure.
Rapidly buried by sediments
Dead organisms that were living million / billion/S of years ago.
Less than 1% of all organisms that die become fossilized.

Amber is fossilized tree resin, while most fossils are made from the remains of organisms.
Fossilized remains of single-celled organisms similar to modern bacteria have been found in rocks more than 1.5 billion years old. These fossils provide valuable insight into Earth's ancient environments and the evolution of early life forms.
