Comparative Paleobiological & Anatomical Matrix
| Feature / Trait | Centrosaurus | Diabloceratops |
|---|---|---|
Total Length | 5.5–6 m (18.0–19.7 ft) Estimated maximum | 4.5–5.5 m (14.8–18.0 ft) Estimated maximum |
Hip Height | 2–2.3 m (6.6–7.5 ft) Model estimate | 1.8–2.1 m (5.9–6.9 ft) Model estimate |
Body Mass | 2.0–3.0 metric tons (4,409–6,614 lbs) Volumetric/allometric model | 1.5–2.0 metric tons (3,307–4,409 lbs) Volumetric/allometric model |
Epoch Horizon | Cretaceous Period 76.5–75.5 Ma (million years ago) | Cretaceous Period 81–79 Ma (million years ago) |
Diet & Trophic Role | Herbivore Herbivorous; processed tough woody shrubs, cycads, and palms with continuously shearing dental batteries. | Herbivore Tough coastal shrubs, palms, and cycads sliced with shearing dental batteries. |
Taxonomic Clade | Ceratopsia(Infraorder) | Ceratopsia(Infraorder) |
Fossil Localities | Dinosaur Park Formation, Alberta, Canada Named: 1902 | Wahweap Formation, Kane County, Utah, United States Named: 2002 |
Locomotion & 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](/dinosaurs/styracosaurus) and duck-billed hadrosaurs like [Corythosaurus](/dinosaurs/corythosaurus). | Basal centrosaurine herbivore with long, curved brow horns and elaborate spike-like parietal frill projections. Inhabiting the Wahweap Formation of Utah, Diabloceratops represents an early evolutionary ancestor to later Campanian horned giants such as [Centrosaurus](/dinosaurs/centrosaurus) and [Styracosaurus](/dinosaurs/styracosaurus). |
Holotype & Fossils | Megabonebeds in Dinosaur Provincial Park yielding thousands of bones and dozens of intact skulls. | Nearly complete articulated skull with intact horn cores and lower jaws (UMNH VP 16699). |
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.
