2. BODY FOSSILS Pa rts of organism bodies.

3. BODY FOSSILS Pa rts of organism bodies. These include teeth, bones, skin, eggs, leaves, wood and bark. Trace fossils are anything made by an organism or left behind by one. Examples are footprints, bodily waste, burrows or the previously mentioned stromatolites. BACK

4. MOLECULAR FOSSILS O rganic molecules derived from once living organisms. .

5. MOLECULAR FOSSILS O rganic molecules derived from once living organisms. They fall within the category of biomarkers (or biosignatures), which are substances or characteristics that indicate a modern or past biological presence, state, or process. BACK

6. TRACE FOSSILS Geological records of the activities and behaviors of past life.

7. TRACE FOSSILS Geological records of the activities and behaviors of past life. Some examples include rock evidence of nests, burrows, footprints, and scat. These fossils are different from body fossils that preserve the actual remains of a body such as shells or bones. BACK

8. CARBON FOSSILS When an organism dies and is buried in sediment

9. When an organism dies and is buried in sediment, the materials that make the organism break down and eventually only the carbon remains. The thin layer of carbon left behind can show an organism's delicate parts like leaves or plant e.g. fern fossil 300 million years old. CARBON FOSSILS BACK

10. Pseudofossils . I norganic  objects, markings, or impressions that might be mistaken for  fossils .

11. Pseudofossils .   I norganic  objects, markings, or impressions that might be mistaken for  fossils . Pseudofossils may be misleading, as some types of mineral deposits can mimic lifeforms by forming what appear to be highly detailed or organized structures. BACK
