If dinosaurs lived millions of years before humans, how do we know so much about them? This series examines the discovery of each featured species and later fossil finds that added to our body of knowledge, explaining how scientists interpret fossils to explain dinosaur behavior. Describes how the Triceratops was discovered, how paleontologists study its bones, and what the fossil evidence tells us about the behavior of this three-horned plant-eating dinosaur.
