    • Abstract:
      Fossil records indicate that Centrosaurus, a single-horned ceratopsid, was a prolific dinosaur that dominated western Laurasia in the latter part of the Late Cretaceous period (99–66 million years ago). Extensive fossil deposits have been discovered in North America and as far east as Asia, demonstrating that ceratopsids migrated between the two continents when they were still joined by a land bridge.
