ECOLOGY AND EXTINCTIONS curriculum kit includes a fragment of a real triceratops frill encased in simulated rock for students to excavate. The kit also includes samples of 65 million year old fossils from Wyoming that represent the habitat that existed when the meteorite killed all dinosaurs, causing the 5th mass extinction in earth's history.  Students will learn about mass extinctions, biology of dinosaurs, reconstructing ancient habitats based on fossils, and evidence of modern extinction events. All activities conform to Next Gen science standards.
