Giganotosaurus 3D Viewer runs one of the largest predatory dinosaurs known - from Late Cretaceous Patagonia - 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 Giganotosaurus page and take the camera

Open the Giganotosaurus 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit the Giganotosaurus 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 Giganotosaurus controls under the canvas

Under the Giganotosaurus 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 12.5 m; holotype skeletons about 12-13 m; a larger referred jawbone MUCPv-95 suggests up to about 13.2 m)

Read the Giganotosaurus facts panel and click body parts

The Giganotosaurus facts panel lists length about 12-13 m for the holotype (up to about 13.2 m for referred specimen MUCPv-95), skull length about 1.53-1.80 m in the holotype and up to about 1.95 m in the larger referred specimen, weight about 4.2-13.8 tonnes with many estimates around 7-8 tonnes, the 99.6-95 Mya early Cenomanian window in the Candeleros Formation of Patagonia, Argentina, and discovery - Ruben Dario Carolini found the first fossils near Villa El Chocon in 1993; Rodolfo Coria and Leonardo Salgado named the species in 1995. Holotype MUCPv-Ch1 is held at the Ernesto Bachmann Municipal Paleontological Museum in Villa El Chocon. The model uses the shared theropod builder with a proportionally larger head (feats.bigHead) to reflect that skull size. A short click - not a drag - on the head, an arm, the tail, or a leg surfaces a short fossil fact; click empty space to return to the species sheet. Skin and color are an artistic reconstruction, not a fossil-accurate skeleton. The model is procedural theropod with no free-licensed Giganotosaurus glTF re-hosted yet.

What the Giganotosaurus how-to guide is not

The Giganotosaurus 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 weight (the wide 4.2-13.8 tonne range is intentional), does not claim Giganotosaurus was definitively larger or smaller than Tyrannosaurus rex, does not invent a specific proven prey list, does not invent a glTF credit, and does not invent game score or win states. For the size story see Giganotosaurus size comparison. For trade-offs versus phone AR apps see Giganotosaurus 3D viewer vs AR apps.
