How to View Parasaurolophus in 3D
Parasaurolophus 3D Viewer runs a crested duck-billed Parasaurolophus in your browser - drag to rotate, scroll or pinch to zoom, toggle a 1.8 m person for scale, and click the long head crest or another body part to read a fossil-sourced fact.
Open the Parasaurolophus page and take the camera
Open the Parasaurolophus 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit the Parasaurolophus 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.
Use the four Parasaurolophus controls under the canvas
Under the Parasaurolophus 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 (about 9.5 m for the Size vs human scale; published length estimates range from about 7.5 m to over 9 m, with some sources citing up to about 11 m)
Read the Parasaurolophus facts panel and click body parts
The Parasaurolophus facts panel lists the real size ranges (length about 7.5 m to over 9 m, some sources up to about 11 m; standing height about 4.4-5.6 m; weight about 2.6 to more than 5 tonnes), the 76.5-73 Mya Late Cretaceous (Campanian) window in western North America, diet Herbivore, and discovery - William Parks named the genus in 1922 from a 1920 find near the Red Deer River, Alberta (type specimen ROM 768). The long hollow crest is an extension of the nasal passages; its exact shape differs by species, and this model shows a representative long form. Crest function is debated (sound resonance, visual recognition, heat regulation) - not settled. A short click - not a drag - on the crest surfaces its own dedicated fact; other parts use the shared head, body, neck, tail, and leg notes. Click empty space to return to the species sheet. Skin and color are an artistic reconstruction, not a fossil-accurate skeleton. No free-licensed Parasaurolophus glTF is re-hosted yet, so the page stays procedural.
What the Parasaurolophus how-to guide is not
The Parasaurolophus 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, does not invent a settled crest function, does not invent a glTF credit, and does not invent game score or win states. For the size story see Parasaurolophus size comparison. For trade-offs versus phone AR apps see Parasaurolophus 3D viewer vs AR apps.
