Five types of fossils are:
1. Mold (imprint) fossils
When a leaf, feather, bone or even a body of an organism leaves an imprint on sediment, which hardens and becomes rock
2. Cast fossils
When minerals fill in the hollows of an animal track, a mollusk shell, or another part of an organism
3. Fossil fuels
Fuels formed by the remains of dead plants and animals
4. Actual remains
It is the body of an organism, with all the parts intact, usually preserved in ice, amber, or tar.
5. Petrified wood
When minerals replace wood or stone to create either petrified wood or a mineralized fossil
