Instructions
Use a map to find a dry riverbed, canyon or wash near your house.
Hike near the banks of the wash or canyon walls. Fossils line the banks and are exposed by erosion and fall into the wash.
Look for exposed sedimentary rock. Dry washes and riverbeds once cut through the earth exposing sedimentary rock formations. Sedimentary rock comes in many colors from light tan to dark red and is characterized by deep horizontal striations in the rock.
Walk slowly and very low to the ground.
Search for unusual lines or patterns in the rock as you walk.
Pick up rocks and Inspect closely with a magnifying glass looking for imprints of small shells or sea animals.
