Trilobite Fossils and Paleontology

Jasmine introduces Dr. Hartsell, a paleontologist, who explains how fossils like petrified wood and trilobites provide evidence of past environments. They discuss how Arizona's petrified wood suggests a non-desert past and how trilobite fossils found in Morocco indicate ancient oceanic conditions. The video highlights the importance of fossils in understanding historical climates and ecosystems.
