Discuss the five major mass extinctions that have occurred in the last 540 million years. Focus on the Permian-Triassic extinction (the "Great Dying," which killed 96% of ocean organisms and 70% of land organisms) and the Cretaceous-Paleogene extinction (which ended the non-avian dinosaurs). Ask a thought-provoking question: "Are we living through the sixth mass extinction today?"
The study of fossils dates back to ancient civilizations, with evidence of fossil collecting and interpretation found in ancient Greece, China, and Egypt. However, the modern discipline of paleontology emerged during the 19th century, with key milestones including:

Beyond curiosity, paleontology is vital for predicting the future. By studying mass extinction events
Let us design a that works for high school or introductory college audiences. Each slide serves a specific purpose in building understanding. Section 3: Fossilization and Taphonomy Age of Mammals
: How paleontology provides data on past climates, biodiversity, and ocean circulation.
The appearance of most major animal phyla (arthropods, mollusks, chordates) in a short geological window. Slide 17: Life Moves to Land
After Slide 8 (Trace Fossils), insert a slide titled: "What can a footprint tell us that a bone cannot?" This encourages students to think about behavior, speed, herd dynamics, and weight versus structural anatomy.
