Chasmosaurus lived in western North America during the late Cretaceous. At the time, the area was a coastal floodplain with rivers and swamps. There were wet and dry seasons. Plants included conifers, such as Sequoia, cycads, ferns, ginkgoes, horsetails, and flowering plants such as palm trees and primitive grasses.
