Anatomy & Physical Characteristics

Centrosaurus was an abundant horned dinosaur of the Dinosaur Park Formation in Alberta, Canada. Measuring six meters in length, it possessed a massive single horn over its snout that often curved forward, two small brow hornlets, and two forward-hooking hook-like horns projecting over the top of its neck frill.

Immense bonebeds containing thousands of Centrosaurus individuals reveal that they traveled in vast migratory herds that suffered mass drownings while crossing flooded Cretaceous rivers.

Diagnostic Morphological Traits

Stout, powerful quadruped with a long nasal horn, scalloped frill with downward-curving hooks, and strong shoulders.

All Herbivore Species

Trophic Guild: Herbivore

Herbivorous; processed tough woody shrubs, cycads, and palms with continuously shearing dental batteries.

Paleobiology & Behavior

Gregarious horned herbivore that gathered in massive herds numbering hundreds of individuals, as demonstrated by catastrophic bonebed deposits. In the Dinosaur Park Formation, Centrosaurus coexisted with fellow ceratopsians like Styracosaurus and duck-billed hadrosaurs like Corythosaurus.

Habitat & Ecological Biome

Prehistoric Depositional Setting

Lowland coastal plains, swamp forests, and coastal floodplains of the Western Interior Seaway.

Cretaceous Period PeriodTemporal Interval: 76.5–75.5 Ma (million years ago)

The longest and final period of the Mesozoic Era, characterized by the rise of flowering plants, ceratopsians, hadrosaurs, tyrannosaurids, and concluding with the Chicxulub asteroid impact.

Where It Lived & Paleoenvironment

North America Dinosaurs

During the Mesozoic Era, continental drift progressively reconfigured land bridges, atmospheric currents, and regional precipitation regimes. Fossils of Centrosaurus evidence its adaptation to the paleoenvironments of North America.

Paleogeographic RealmNorth America (North America)

Home to the fossil-rich Morrison Formation of the Late Jurassic and the Hell Creek and Dinosaur Park Formations of the Late Cretaceous.
