How to View Dilophosaurus in 3D
Dilophosaurus 3D Viewer runs an Early Jurassic Dilophosaurus - a twin-crested theropod from Arizona - in your browser. Drag to rotate, scroll or pinch to zoom, toggle a 1.8 m person for scale, and click the head, an arm, the tail, or a leg for a fossil-sourced fact.
Open the Dilophosaurus page and take the camera
Open the Dilophosaurus 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit the Dilophosaurus 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 Dilophosaurus controls under the canvas
Under the Dilophosaurus 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 6.03 m from holotype UCMP 37302; largest known specimen near about 7 m)
Read the Dilophosaurus facts panel and click body parts
The Dilophosaurus facts panel lists length about 6.03 m for the holotype (largest known near about 7 m; Size vs human uses about 6.03 m), weight about 283 kg for the holotype (largest known up to about 400 kg), the 195-184 Mya Early Jurassic window (often cited around 193 Mya) in the Kayenta Formation of northern Arizona, and discovery - Samuel Welles described the fossil in 1954 as a Megalosaurus species, then created the genus Dilophosaurus ("two-crested lizard") in 1970. A pair of thin arched crests ran along the skull top (nasal and lacrimal bones), rendered here as two offset fins via a page-local rewrite of feats.crest. Jurassic Park (1993) added a deployable neck frill and venom spit for drama - neither has fossil support. A short click - not a drag - on the head (including the crest area), an arm, the tail, or a leg surfaces a short fossil fact; click empty space to return to the species sheet. Skin color and exact crest covering are an artistic reconstruction; the model is procedural theropod with no free-licensed Dilophosaurus glTF re-hosted yet.
What the Dilophosaurus how-to guide is not
The Dilophosaurus 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 one precise length or weight, does not invent a neck frill or venom spit, does not invent a glTF credit, and does not invent game score or win states. For the size story see Dilophosaurus size comparison. For trade-offs versus phone AR apps see Dilophosaurus 3D viewer vs AR apps.
Why trust these tools
