How to View Pachyrhinosaurus in 3D
Pachyrhinosaurus 3D Viewer runs a Late Cretaceous Pachyrhinosaurus - a horned-dinosaur relative of Triceratops with thick bony bosses instead of long horns - in your browser. Drag to rotate, scroll or pinch to zoom, toggle a 1.8 m person for scale, and click a body part for a fossil-sourced fact.
Open the Pachyrhinosaurus page and take the camera
Open the Pachyrhinosaurus 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit the Pachyrhinosaurus with the pointer and zoom with the scroll wheel or a two-finger pinch. Fullscreen expands the wrapper so the controls stay visible beside the scene. After first paint a license-clean glTF may swap in automatically; if that load fails the page stays on the procedural body with zero regression.
Use the four Pachyrhinosaurus controls under the canvas
Under the Pachyrhinosaurus canvas, four controls handle view and scale:
- Fullscreen - fills the display while keeping the buttons visible
- Stop rotation / Auto-rotate - freezes or resumes auto-spin
- Idle motion - adds subtle breathing and leg sway; tap again for Stand still
- Size vs human - shows a 1.8 m person at the honest length ratio used by the viewer (8 m within the commonly cited about 6-8 m range for P. canadensis)
Read the Pachyrhinosaurus facts panel and click a body part
The Pachyrhinosaurus facts panel lists length about 6-8 m for the type species P. canadensis (Size vs human uses 8 m; some sources such as Britannica cite a smaller about 6 m figure), weight about 3-4 metric tons for P. canadensis (spec shows 4000 kg; Britannica about 1.8 t is disclosed as source variance), thick flattened bony bosses on the nose and above the eyes instead of Triceratops-style long brow horns, a frill with small margin spikes in some individuals, a beaked herbivore mouth, the Late Cretaceous window about 73.5 to 71 million years ago (Campanian-Maastrichtian), and naming history - Charles M. Sternberg named the genus in 1950 from holotype NMC 8867 collected 1945-1946 in the Horseshoe Canyon Formation, Alberta, Canada. A related species, P. lakustai, comes from the Pipestone Creek bonebed found by schoolteacher Al Lakusta in 1974; a 2024 excavation there uncovered a large skull nicknamed "Big Sam" (about 138 cm long with a 43 cm nasal boss). A short click - not a drag - on head, body, neck, tail, leg, or frill surfaces a short fossil fact. Procedural skin color is an artistic choice; when the CC-BY 4.0 SUMO STUDIOS glTF loads, the status text notes a real model with that credit - a stylized low-poly reconstruction, not a laser scan.
What the Pachyrhinosaurus how-to guide is not
The Pachyrhinosaurus how-to guide is a controls walkthrough for the in-browser viewer only - it does not place the model in your room (no AR), does not claim soft-tissue or color accuracy for the procedural body, does not invent one precise length or weight beyond the disclosed ranges, does not claim Pachyrhinosaurus had long horns, does not invent game score or win states, and does not claim the optional glTF is a scientifically exact reconstruction.
