Drag to rotate the Shuangmiaosaurus, scroll or pinch to zoom, and click a body part - the head, a limb, or the tail - to read what fossils tell us about it. The panel beside the model carries the real figures.
Shuangmiaosaurus was a basal hadrosauroid from mid-Cretaceous China - turn on the human figure to see how a person compares to its roughly 7.5 m body.
The colors and skin here are an artistic reconstruction; fossils preserve bone, not soft tissue or color. This genus is known from jaw fragments only, so the body outline is highly interpretive. This model is not a fossil-accurate skeleton. The measurements in the panel follow published estimates, with ranges shown where sources disagree.
Shuangmiaosaurus 3D Viewer
This page renders a Shuangmiaosaurus 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, a limb, or the tail to read a fact about that part.
Shuangmiaosaurus lived about 106-100 million years ago in the mid-Cretaceous (Late Albian to Cenomanian) of northeastern China (Sunjiawan Formation near Shuangmiao, Beipiao, Liaoning). You et al. named S. gilmorei in 2003 from jaw fragments (holotype LPM 0165). Common published size estimates are about 7.5 m and about 2.5 tonnes; hip height is poorly constrained from the jaws alone, so this page uses about 2.5 m as a reconstruction baseline for a bipedal hadrosauroid of that length.
| Measure | Figure |
|---|---|
| Length | about 7.5 m (common published estimate) |
| Hip height | about 2.5 m (panel reconstruction baseline; jaws only) |
| Weight | about 2.5 tonnes (panel baseline 2500 kg) |
| When it lived | about 106-100 million years ago (mid-Cretaceous, Late Albian to Cenomanian) |
| Diet | Herbivore |

Frequently Asked Questions
How big was Shuangmiaosaurus?
Common published estimates put Shuangmiaosaurus at about 7.5 m long and about 2.5 tonnes. The holotype is jaw material only, so mass and hip height are reconstructed from comparisons with related hadrosauroids. This page uses 7.5 m, about 2.5 m hip height, and 2500 kg as the facts-panel baselines. Turn on the human figure in the viewer to see the scale against a 1.8 m person.
What kind of dinosaur was it?
Shuangmiaosaurus gilmorei is a basal hadrosauroid - an iguanodontian ornithopod close to, but outside, Hadrosauridae (You et al. 2003). It was a herbivore with a duck-billed feeding style at the jaws, but it is not a hadrosaurid duckbill in the narrow sense.
When and where did Shuangmiaosaurus live?
In mid-Cretaceous northeastern China, about 106 to 100 million years ago (Late Albian to Cenomanian), in the Sunjiawan Formation near Shuangmiao, Beipiao, Liaoning. You et al. named the genus in 2003.
Is the model scientifically accurate?
The length and mass figures follow published estimates, but the skin color and soft-tissue outline are an artistic reconstruction - fossils preserve bone, not soft tissue or color. This genus is known from jaw fragments only, so the body shape is highly interpretive. This model is not a fossil-accurate skeleton.
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.
