How to View Megalosaurus in 3D
Megalosaurus 3D Viewer runs the first dinosaur scientifically named - Buckland 1824 - a Middle Jurassic theropod about 6-9 m long (Size vs human uses 7 m), mass about 0.7-1.1 tonnes. 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 Megalosaurus page and take the camera
Open the Megalosaurus 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit Megalosaurus 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 Public Domain glTF may swap in automatically from the CDN; if that load fails the page stays on the procedural theropod with zero regression.
Use the four Megalosaurus controls under the canvas
Under the Megalosaurus 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 (7 m representative within the published about 6-9 m range)
Read the Megalosaurus facts panel and click a body part
The Megalosaurus facts panel lists length about 6-9 m (NHM directory about 6 m; Owen historically about 9 m; Paul 2010 about 6 m; Size vs human uses 7 m), hip height about 2-2.5 m for a large adult, mass about 0.7-1.1 tonnes (Paul about 700 kg; Benson femur-based about 0.9 t), the Middle Jurassic window about 168-166 million years ago (Bathonian) of England, carnivore diet, and naming - William Buckland described Megalosaurus bucklandii in 1824 as the first valid dinosaur genus. A short click - not a drag - on head, body, leg, or tail surfaces a short fossil fact. Procedural skin color is an artistic choice; when the Public Domain glTF by Model Magic via Printables loads, the status text notes a real model with that credit - a stylized reconstruction, not a laser scan. This model is not a fossil-accurate skeleton and does not claim Victorian 20 m lizard reconstructions were accurate.
What the Megalosaurus how-to guide is not
The Megalosaurus 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 6-9 m / 0.7-1.1 tonne ranges, does not revive Victorian oversize lizard reconstructions, 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.
