How to View Therizinosaurus in 3D
Therizinosaurus 3D Viewer runs a Late Cretaceous Therizinosaurus - the giant herbivorous theropod with the longest claws of any known land animal - in your browser. Drag to rotate, scroll or pinch to zoom, toggle a 1.8 m person for scale, and click a body part (including a giant hand claw) for a fossil-sourced fact.
Open the Therizinosaurus page and take the camera
Open the Therizinosaurus 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit the Therizinosaurus 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 Therizinosaurus controls under the canvas
Under the Therizinosaurus 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 within the published 9-10 m length range)
Read the Therizinosaurus facts panel and click a giant claw
The Therizinosaurus facts panel lists length about 9-10 m, height about 4-5 m, weight about 5-10 tonnes depending on method (the Natural History Museum, London, does not commit to a single mass figure), hand-claw bone cores just above 50 cm - the longest claws of any known land animal - the ~72-66 Mya Late Cretaceous window (Maastrichtian, possibly late Campanian) in the Nemegt Formation of the Gobi Desert, Mongolia, and naming history - Evgeny Maleev named the genus in 1954 from holotype PIN 551-483, discovered in 1948. Despite predator-like claws it was a herbivore (high-browser). Overall body shape is inferred from more complete relatives (Beipiaosaurus, Nothronychus), not from this genus alone; feathering is inferred from Beipiaosaurus, not directly observed on Therizinosaurus. It has a long neck, a toothless beak, and dramatically enlarged forelimbs (feats.longArms with oversized claws). A short click - not a drag - on a giant claw surfaces the dedicated giant-claw fact; click elsewhere for head, body, tail, leg, or neck facts; click empty space to return to the species sheet. Skin color is an artistic reconstruction; the model is procedural with no free-licensed Therizinosaurus glTF re-hosted yet.
What the Therizinosaurus how-to guide is not
The Therizinosaurus 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 beyond the cited 5-10 t range, does not claim body shape or feathering is settled from this genus alone, does not claim it was a predator, does not invent a glTF credit, and does not invent game score or win states.

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.
