Those surrounded by skeletal structures
There are four types of fossils that can be found. These are true fossils, mold fossils, trace fossils and cast fossils.
The most usually fossilized parts of organisms are bones and shells. These are least likely to rot or wear away before they are buried and mineralised. In rare instances the soft parts of the bodies are preserved and are normally shown as thin films on the rock surface.
Yes, fossils are real. They are mineralized remains of hard parts (bones/teeth/wood) or imprints of once living organisms.
Organisms with hard parts such as a mineralized shell, like a trilobite or ammonite, are much more likely to become fossilized than animals with only soft parts.
These are called "replacement fossils" also "petrification"
Ones with hard bony parts, soft tissues do not from fossils.
Harder parts of organisms become fossils. For example vasculature in plants and bones of animals are best preserves in the fossils.

When an organism dies, its soft parts often decay quickly or are eaten by animals
Tar is known as Asphalt fossils. Asphalt preserve only hard parts of organisms such as teeth, bones and the outer shells of spiecies. Countless numbers of these fossils are preserved in tar pits.

No. The hard bones are more likely to form a fossil. The soft parts will degenerate over time. This is why most of the fossils from the Pre-Cambrian and Cambrian periods are mostly shells, not the actual animals that inhabited them.
Yes, footprints that are preserved in rock, such as those of extinct dinosaurs, are fossils. Such fossils are known as ''trace fossils'' , as opposed to ''body fossils'' which are fossilized remnants of the hard parts of these ancient organisms.
organisms tend to decay before becoming a fossil. animals with hard parts are preserved more easily. geological processes may destroy fossils.
no fossils of organisms with hard parts. the few soft body part fossils found rarely fossilize well.
