There are four types of fossils that can be found. These are true fossils, mold fossils, trace fossils and cast fossils.
one kind of fossil forms from the body parts of organisms. what is another kind of fossil

Cast :)
Cast
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.
It is called a mold fossil, which can become a cast fossil. After the soft parts of the animal rot away, a cavity remains (the mold fossil) which becomes filled with hardened sand or mud (the cast fossil).
These organisms eat other organisms, parts or product of other organisms or the remains of the organisms

organisms tend to decay before becoming a fossil. animals with hard parts are preserved more easily. geological processes may destroy fossils.
Most life-forms were single celled, with no hard parts to fossilize.

Most life-forms were single-celled, with no hard parts to fossilize.
Harder parts of organisms become fossils. For example vasculature in plants and bones of animals are best preserves in the fossils.
A cast fossil is formed when minerals fill in an impression left by an organism.
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.
The fossil record is incomplete because: A.) very few organisms were preserved as fossils. B.) organisms tend to decay before becoming a fossil. C.) animals with hard parts are preserved more easily. D.) geological processes may destroy fossils. E.) all of these. ALL OF THESE!
