Drag to rotate the Qianzhousaurus, scroll or pinch to zoom, and click a body part - the head, the tail, or a leg - to read what fossils tell us about it. The panel beside the model carries the real figures.
Qianzhousaurus was a tyrannosaurid with an unusually long, narrow snout - about 70 percent of the skull length - unlike the short, deep snout of larger relatives such as Tyrannosaurus rex. The holotype stood about 2 m tall at the hip and stretched roughly 6.3 m from snout to tail; turn on the human figure to see how far a person's head would reach.
The colors and skin here are an artistic reconstruction; fossils preserve bone, not soft tissue or color. The measurements in the panel are the real published ones.

This page renders Qianzhousaurus as a 3D model you can spin in the browser: drag to rotate, pinch to zoom, add a 1.8 m person for scale, and click a body part for a fact.
Qianzhousaurus sinensis was a tyrannosaurid that lived in the Late Cretaceous, roughly 72-66 million years ago, in what is now southeastern China. Its most distinctive feature is a long, narrow snout studded with small horn-like bumps, making up about 70 percent of its skull length - very different from the short, deep, muscular snout of Tyrannosaurus rex. That difference earned it the nickname Pinocchio rex in early press coverage. Junchang Lu and colleagues named it in 2014 from a nearly complete skull and partial skeleton found at a construction site near Ganzhou, in the Nanxiong Formation.
The holotype individual is estimated at about 6.3 m long, 2 m tall at the hip, and 750-757 kg. Because the holotype may not have been fully grown, some researchers estimate that larger individuals could reach roughly 7.5-9 m. This page uses the holotype figures as its panel baseline and notes the wider range here because sources disagree on adult size.

Skin tone and pattern are an artistic reconstruction, since fossils preserve no color or soft tissue; the numbers above are real published values. Qianzhousaurus belongs to the same tyrannosaurid family as the already-shipped Tyrannosaurus rex 3D Viewer and Albertosaurus 3D Viewer, but its long snout sets it apart from both.
Frequently Asked Questions
Why is Qianzhousaurus called Pinocchio rex?
Its snout is unusually long and narrow for a tyrannosaurid, making up about 70 percent of the skull length, unlike the short, deep snout of Tyrannosaurus rex. Early press coverage of the 2014 description nicknamed it Pinocchio rex for that long nose.
How big was Qianzhousaurus?
The holotype individual is estimated at about 6.3 m long and 2 m tall at the hip, weighing 750-757 kg. Because the holotype may not have been fully grown, some researchers estimate larger individuals could reach roughly 9 m. Turn on the human figure in the viewer to see the scale against a 1.8 m person.
Is the model scientifically accurate?
The proportions follow a standard tyrannosaurid body plan - the source model does not sculpt the exaggerated long snout in full detail - but the skin color and texture are an artistic reconstruction regardless. Fossils preserve bone, not soft tissue or color. The length, weight, and age figures shown are the real published values.
When and where did Qianzhousaurus live?
In the Late Cretaceous, roughly 72 to 66 million years ago, in what is now southeastern China. Junchang Lu and colleagues named it in 2014 from a nearly complete skull and partial skeleton found at a construction site near Ganzhou, in the Nanxiong Formation.
Do I need to install anything to view it?
No. The model renders in your browser with WebGL - no app, no account, and nothing about your visit is sent to a server. The 3D engine loads once and is then cached. When available, a free-licensed glTF model may swap in after first paint.
