Most of us have known something about dinosaurs from when we were young. It could have been dinosaur toys. Maybe it was being entertained by Barney on television. Perhaps it was being terribly scared by the Jurassic Park movies. Dinosaurs are definitely a component of popular culture. However, from the scientific perspective, there is an incredible amount that we don't know about them. Many basic things, such as their size, appearance and their eventual demise, pose one of the most fascinating chapters of life on Earth. This course examines the current scientific research examining how and why they evolved and how they lived. The various families of dinosaurs will be explored. The origins of birds, who seem to be the only survivors of the dinosaur lineage, will also be presented.
