Lambeosaurus amongst a herd of Corythosaurus
Both are large hadrosaurs from Campanian North America! Unlike modern mammals, herbivorous dinosaurs had a tendency towards endemism: That is, they were typically found in singular locations. Both Corythosaurus and Lambeosaurus are only found in Alberta, despite Corythosaurus being widespread within Alberta, implying geographic restriction. Lambeosaurus magnicristatus, meanwhile, seems to be fairly rare. Many hadrosaurs tended to live in vast herds, and used their large crests for noisemaking and social signalling.
