Albertaceratops in 3D - click the brow horns, the frill, or a shoulder for a fact (full controls on the Dinosaurs 3D hub).
Albertaceratops was a Late Cretaceous centrosaurine from Alberta with unusually long brow horns for its group; turn on the human figure to see how a person compares to its body.
The measurements in the panel follow published estimates, with ranges shown where sources disagree.
Albertaceratops 3D Viewer
Rotate this Albertaceratops model with a drag, zoom in with scroll or pinch, and size it against a 1.8 m person standing next to it. Three clickable spots - the brow horns, the frill, and a shoulder - each surface a short fact.
A row of buttons under the scene controls the view. The model turns slowly on its own, and Stop rotation freezes it so you can hold one angle; Idle motion switches on a subtle animation so the pose is not perfectly still; Fullscreen opens the viewer edge to edge for a closer look at the frill and horns. The same controls are available on phone and desktop.
Albertaceratops lived in the Late Cretaceous, about 80 to 75 million years ago (often cited near 77.5 Mya), in Alberta. Length estimates run about 5.8 to 7 m; mass about 2 to 3.5 tonnes. It is a basal centrosaurine with long brow horns unusual for that group - different from Triceratops (later chasmosaurine) and from Pachyrhinosaurus (nasal boss, short brow horns).

Frequently Asked Questions
Why are Albertaceratops brow horns unusual?
Most centrosaurines have short brow horns. Albertaceratops combines long brow horns with an otherwise centrosaurine skull, which is why it stands out among Alberta horned dinosaurs.
How big was Albertaceratops?
Published estimates usually fall around 5.8 to 7 m long and about 2 to 3.5 tonnes. The NHM directory lists 7.0 m. Turn on the human figure to see the scale against a 1.8 m person.
When and where did it live?
In the Late Cretaceous, about 80 to 75 million years ago (often cited near 77.5 Mya), in Alberta (Oldman Formation). Related remains have also been discussed from Montana beds of similar age.
How is it different from Triceratops or Pachyrhinosaurus?
Triceratops is a later chasmosaurine with three facial horns. Pachyrhinosaurus has a large nasal boss and short brow horns. Albertaceratops is an earlier centrosaurine with long brow horns. This site has separate viewers for comparison.
Is the model scientifically accurate?
The proportions follow published figures, but soft-tissue color is an artistic reconstruction. This model is not a fossil-accurate skeleton. Length, weight, and age figures are real published values, with ranges cited because sources vary.
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. When available, a free-licensed glTF model may swap in after first paint.
