EASC 135 Dinosaur Evolution and Extinction Dinosaurs were one of the most successful groups of organisms on Earth, and still exist today as birds. What is the evidence for diet, running speed, or for behavior associated with bizarre adaptations like head ornaments or super long necks? You will explore fossil evidence and scientific methods to answer questions about evolutionary relationships, physiology, behavior, past environments and extinction. Labs provide a hands-on introduction to fossils, rocks and fundamental concepts of natural history, geology and paleontology.
