Comparative Paleobiological & Anatomical Matrix
| Feature / Trait | Styracosaurus | Centrosaurus |
|---|---|---|
Total Length | 5–5.8 m (16.4–19.0 ft) Estimated maximum | 5.5–6 m (18.0–19.7 ft) Estimated maximum |
Hip Height | 1.8–2.2 m (5.9–7.2 ft) Model estimate | 2–2.3 m (6.6–7.5 ft) Model estimate |
Body Mass | 2.5–3.2 metric tons (5,512–7,055 lbs) Volumetric/allometric model | 2.0–3.0 metric tons (4,409–6,614 lbs) Volumetric/allometric model |
Epoch Horizon | Cretaceous Period 75.5–75 Ma (million years ago) | Cretaceous Period 76.5–75.5 Ma (million years ago) |
Diet & Trophic Role | Herbivore Tough, fibrous plants such as palms, cycads, and ferns clipped by a sharp keratinous beak and shredded by dental batteries. | Herbivore Herbivorous; processed tough woody shrubs, cycads, and palms with continuously shearing dental batteries. |
Taxonomic Clade | Ceratopsia(Infraorder) | Ceratopsia(Infraorder) |
Fossil Localities | Red Deer River, Alberta, Canada Named: 1913 | Dinosaur Park Formation, Alberta, Canada Named: 1902 |
Locomotion & Behavior | Prominently spiked centrosaurine ceratopsian possessing an impressive frill adorned with long horns and spikes. In the Dinosaur Park Formation, Styracosaurus lived sympatrically with closely related horned dinosaurs like [Centrosaurus](/dinosaurs/centrosaurus) and crested hadrosaurs like [Corythosaurus](/dinosaurs/corythosaurus). | 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](/dinosaurs/styracosaurus) and duck-billed hadrosaurs like [Corythosaurus](/dinosaurs/corythosaurus). |
Holotype & Fossils | Holotype CMN 344 consists of a nearly complete skull; multiple partial skeletons recovered from mass mortality bonebeds. | Megabonebeds in Dinosaur Provincial Park yielding thousands of bones and dozens of intact skulls. |
Paleontological Uncertainty Advisory: Anatomical dimensions, body masses, and metabolic rates are scientific estimates derived from volumetric scaling, laser scanning, and biomechanical limb bone allometry. Missing traits indicate non-preserved fossil elements rather than anatomical absence.
