Drag to rotate the Tyrannosaurus rex, scroll or pinch to zoom, and click a body part - the head, tail, or a leg - to read what fossils tell us about it. The panel beside the model carries the real figures.
A Tyrannosaurus rex stood about 3.7 m tall at the hips and stretched roughly 12.3 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.
Tyrannosaurus rex 3D Viewer
This page renders a Tyrannosaurus rex as a 3D model you can spin in the browser - drag to rotate, scroll or pinch to zoom, toggle a 1.8 m person beside it for scale, and click the head, tail, or a leg to read a fact about that part.
Tyrannosaurus rex lived in the Late Cretaceous, roughly 68 to 66 million years ago, in what is now western North America. It measured about 12.3 m long and 3.7 m tall at the hips, and weight estimates center near 8.9 tonnes. Its jaws held around 60 serrated teeth, some up to 20 cm long including the root.
The first named skeleton was described in 1902 from a find in Montana by Barnum Brown. The model shows the classic short two-fingered arms and the heavy, balanced tail that let this predator carry a large head.

Everything runs on your device with WebGL, so the model works without an account and without sending anything to a server. The skin tone and pattern are an artistic reconstruction, because fossils do not preserve color or soft tissue; the numbers above are real published values.
Frequently Asked Questions
How big was Tyrannosaurus rex?
About 12.3 m long and 3.7 m tall at the hips, with weight estimates near 8.9 tonnes. 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 the fossil skeleton, but the skin color and texture are an artistic reconstruction - fossils preserve bone, not soft tissue or color. The length, weight, and age figures shown are real published values.
When and where did T. rex live?
In the Late Cretaceous, roughly 68 to 66 million years ago, in what is now western North America. The first named skeleton was described in 1902 from a Montana find.
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.
