Parasaurolophus, a distinctive crested dinosaur of Late Cretaceous North America, roamed in herds. Fossil evidence in the Two Medicine Formation, primarily in Montana, reveals its hollow, tube-like crest, possibly used for communication. This herbivorous dinosaur, around 30 feet long, likely lived in diverse environments.
