Why? These two shark teeth were found near Hart Park. Why do you think there are shark teeth buried in the San Joaquin Valley? SJVRocks!! CSUBakersfield Department of Geological Sciences
Objective: We will create a model that explains the presence of marine fossils in the San Joaquin Valley using the Plate Tectonic Theory to help us understand the change of geography over time. SJVRocks!! CSUBakersfield Department of Geological Sciences
