Scolosaurus shared its paleoenvironment with other dinosaurs, such as the duck-billed hadrosaurs Hypacrosaurus, Acristavus, Gryposaurus, Brachylophosaurus, Glishades, Prosaurolophus and Maiasaura, and the ankylosaur Edmontonia. Volcanic eruptions from the west periodically blanketed the region with ash, resulting in large-scale mortality, while simultaneously enriching the soil for future plant growth.
