Fossils

Key Questions

• What is a trace fossil and what can be learned from them?

  Answer:

  A trace fossil is an impression made by an organism not the organism itself

  Explanation:

  Examples of trace fossils are foot prints, impression of leaves on soil, tubes left by worms, Any evidence of the existence of living things is a trace fossil.

  An unusable example of a trace fossil was a spark plug I found fossilized in the strata of Sunset Bay Oregon. The spark plug is evidence of a living thing a human.

  Trace fossils give clues of how living things lived in the past.
