Drag to rotate the Styracosaurus, scroll or pinch to zoom, and click a body part - the frill, the nose horn, or a leg - to read what fossils tell us about it. The panel beside the model carries the real figures.
A Styracosaurus carried a bony frill ringed with long spikes at the back of its skull and a single large horn on its nose, a very different arrangement from the twin brow horns of Triceratops - turn on the human figure to see how the whole animal compares to a person.
The colors and skin pattern here are an artistic reconstruction; fossils preserve bone, not soft tissue or color. The frill, spike, and horn proportions follow the fossil skeleton, but the measurements in the panel are the ones actually published.

This page renders a Styracosaurus 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 frill, the nose horn, or a leg to read a fact about that part.
Styracosaurus lived in the Late Cretaceous, roughly 76 to 75 million years ago, in what is now Alberta, Canada. Published length estimates put adults at about 5 to 5.5 m, with a shoulder height around 1.8 m and a weight commonly cited between about 1,800 and 2,700 kg depending on the source. Its most distinctive feature was a bony frill ringed with four to six long spikes radiating from the neck edge, paired with a single large horn on the nose and no long brow horns - a very different frill shape from the twin-brow-horned Triceratops. A parrot-like beak and rows of cutting and grinding teeth suited it to tough, low-growing plants.
The genus was named in 1913 by Canadian paleontologist Lawrence Lambe. Its first fossils were found the same year at what is now Dinosaur Provincial Park, a UNESCO World Heritage Site in Alberta that has since produced dozens of dinosaur species, and further excavation work at the site has continued since, including a notable 2006 project led by the Royal Tyrrell Museum.

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, and a range is shown where sources vary rather than because a single figure is invented.
Frequently Asked Questions
How big was a real Styracosaurus?
Most published estimates put an adult at about 5-5.5 m long and roughly 1,800-2,700 kg, with a shoulder height around 1.8 m. Turn on the human figure in the viewer to see the true scale against a 1.8 m person.
How is Styracosaurus different from Triceratops?
Styracosaurus had a single large horn on its nose and no long brow horns, with a frill ringed by four to six long spikes. Triceratops instead had two long brow horns, a short nose horn, and a solid frill without long spikes. Both are ceratopsians from the Late Cretaceous of North America.
What were the frill spikes for?
Paleontologists think the spiked frill likely served for display and species recognition, and possibly for defense, similar to the reasoning applied to other horned ceratopsians. The frill and horn shapes come directly from the fossil skull.
Is the model scientifically accurate?
The frill, spike, and horn 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 Styracosaurus live?
In the Late Cretaceous, roughly 76 to 75 million years ago, in what is now Alberta, Canada. The genus was named in 1913 by Lawrence Lambe, with its first fossils found the same year at what is now Dinosaur Provincial Park, a UNESCO World Heritage Site.
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.
