How to View Edmontosaurus in 3D
Edmontosaurus 3D Viewer runs a crestless duck-billed Late Cretaceous hadrosaur known for mummified skin fossils. 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 Edmontosaurus page and take the camera
Open the Edmontosaurus 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit Edmontosaurus 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 Edmontosaurus controls under the canvas
Under the Edmontosaurus 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 (10 m representative within the published about 9-12 m adult range)
Read the Edmontosaurus facts panel and click a body part
The Edmontosaurus facts panel lists typical adult length about 9-12 m (Size vs human uses 10 m), average mass about 5.6 tonnes with exceptionally large individuals estimated up to about 15 tonnes or more, the Late Cretaceous window about 73 to 66 million years ago in western North America, a broad toothless beak for cropping plants, and no bony head crest - a clear contrast with the already-shipped crested Parasaurolophus. Naming history: Lawrence Lambe named the type species E. regalis in 1917 from Alberta's Horseshoe Canyon Formation; E. annectens was described earlier in 1892 by O.C. Marsh as Claosaurus annectens from Wyoming's Lance Formation. Famous mummified specimens with skin impressions include the 1908 AMNH 5060 "Trachodon mummy" and the 1999 "Dakota" specimen. Large bonebeds suggest herd living. A short click - not a drag - on head, body, neck, 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 Edmontosaurus how-to guide is not
The Edmontosaurus 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 9-12 m / ~5.6 t (up to ~15 t) figures, does not claim a bony crest, 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.
