Dinosaurs are sexy creatures. They are icons of both evolution and extinction, and are our most beloved fossil celebrities. But we can’t learn everything we need to know from studying the bones of dinosaurs themselves. Charismatic as they were, dinosaurs were only part of ancient ecosystems, and reconstructing the world of the dinosaurs requires additional lines of evidence.
