How to View Carnotaurus in 3D
Carnotaurus 3D Viewer runs a Late Cretaceous Carnotaurus - a horned, short-armed abelisaurid from 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 Carnotaurus page and take the camera
Open the Carnotaurus 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit the Carnotaurus 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 Carnotaurus controls under the canvas
Under the Carnotaurus 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 7.8 m from the about 7.5-8 m core estimate for the single known skeleton; other estimates from that holotype run as high as about 9 m)
Read the Carnotaurus facts panel and click body parts
The Carnotaurus facts panel lists length about 7.5-8 m (other estimates from the same skeleton up to about 9 m; Size vs human uses about 7.8 m), weight about 1.3-2.1 tonnes, the 69-66 Mya Late Cretaceous (Maastrichtian) window in the La Colonia Formation of Chubut Province, Argentina, and discovery - Jose Bonaparte named Carnotaurus sastrei in 1985 from a single skeleton. A pair of thick conical brow horns sat above the eyes - the only theropod on this site with the horns feature. Forelimbs were even more reduced than a Tyrannosaurus rex's, with tiny barely functional fingers. The holotype preserves real skin impressions - a mosaic of small non-overlapping bumpy scales with no feather evidence - but the tail and lower legs were never recovered, so those parts are inferred from close abelisaurid relatives. A short click - not a drag - on the head (including the horn area), an arm, the tail, or a leg surfaces a short fossil fact; click empty space to return to the species sheet. Skin color is an artistic reconstruction, not a fossil-accurate skeleton. The model is procedural theropod with feats.horns and no free-licensed Carnotaurus glTF re-hosted yet.
What the Carnotaurus how-to guide is not
The Carnotaurus 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 claim the tail and lower legs are known from the holotype, does not invent a glTF credit, and does not invent game score or win states. For the size story see Carnotaurus size comparison. For trade-offs versus phone AR apps see Carnotaurus 3D viewer vs AR apps.
Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
