How to View Protoceratops in 3D
Protoceratops 3D Viewer runs a small, hornless Late Cretaceous ceratopsian famous for the Fighting Dinosaurs fossil locked with a Velociraptor. 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 Protoceratops page and take the camera
Open the Protoceratops 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit Protoceratops 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 CC-BY-SA 4.0 glTF may swap in automatically; if that load fails the page stays on the procedural body with zero regression.
Use the four Protoceratops controls under the canvas
Under the Protoceratops 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 (2 m representative within the published about 1.8-2.5 m range)
Read the Protoceratops facts panel and click a body part
The Protoceratops facts panel lists length about 1.8-2.5 m across sources (Size vs human uses 2 m), weight about 62-245 kg depending on the source (AMNH about 1.8 m / 225 kg; other sources about 2 m / 180 kg or 62-104 kg), the Late Cretaceous window about 75 to 71 million years ago in the Djadokhta Formation of Mongolia's Gobi Desert, a modest bony frill with a parrot-like beak and no brow or nose horns - a clear contrast with shipped Triceratops and Pachyrhinosaurus - and the 1971 Fighting Dinosaurs fossil (MPC-D 100/512 locked with Velociraptor MPC-D 100/25). Discovery: J. B. Shackelford found the first specimen on 2 September 1922 during Roy Chapman Andrews's AMNH Central Asiatic Expeditions; Walter W. Granger and William K. Gregory described the genus in 1923 from holotype AMNH 6251. A short click - not a drag - on head, body, frill, tail, or leg surfaces a short fossil fact. Procedural skin color is an artistic choice; when the CC-BY-SA 4.0 glTF by seth the yutyrannus (via Printables) loads, the status text notes a real model with that credit - a stylized reconstruction, not a laser scan.
What the Protoceratops how-to guide is not
The Protoceratops 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 invent one precise length or weight beyond the disclosed about 1.8-2.5 m / 62-245 kg ranges, does not claim brow or nose horns, does not claim soft-tissue accuracy for the procedural body, does not invent game score or win states, and does not claim the optional glTF is a scientifically exact reconstruction.
