What happened here?

Fossils are the remains of once-living plants and animals. In this activity, you will interpret animal activity from the pattern of fossil footprints.

Williams Station Power Plant

Procedure

1. Read and complete the lab safety form.

2. Study the photograph of a set of footprints that have been preserved in sedimentary rock.

3. Write a description of how these tracks might have been made.

4. Draw your own diagram of a set of fossilized footprints that records the interactions of organisms in the environment.

5. Give your diagram to another student and have him or her interpret what happened.

Analysis

1. Determine the number of animals that made these tracks.

2. Infer types of information that can be obtained by studying fossil footprints.

3. Interpret another group's diagram. Is your answer the same as theirs? What might have caused any differences?

STEP 1 Mark the middle of a vertical sheet of paper. Fold the top and bottom to the middle to form two flaps.

STEP 2 Fold into thirds.

STEP 3 Unfold the paper and cut the flaps along the fold lines as shown.
