Alioramus in 3D - click the head, a limb, or the tail for a fact (full controls on the Dinosaurs 3D hub).
Alioramus was a Late Cretaceous long-snouted tyrannosaurid from Mongolia - turn on the human figure to see how a person compares to its roughly 5.5 m body.
The measurements in the panel follow published estimates, with ranges shown where sources disagree.
Alioramus 3D Viewer
Rotate the Alioramus below by dragging, zoom in with the scroll wheel, and click a body part to reveal a fact (see the Dinosaurs 3D hub for every control).
Four buttons sit under the scene. The model turns on a slow automatic turntable by default, so Stop rotation freezes it when you want to line up a single angle, and Idle motion layers on a gentle sway for a more lifelike pose. Fullscreen expands the viewer to fill the screen for a closer look, and the controls stay visible while you explore.
Alioramus lived in the Late Cretaceous of Mongolia (Nemegt Formation), about 72-66 million years ago. Sergei Kurzanov named Alioramus remotus in 1976; a second species, A. altai, was named by Brusatte and colleagues in 2009. It is a slender, long-snouted tyrannosaurid in the tribe Alioramini, distinct from the much larger contemporary Tarbosaurus.

Frequently Asked Questions
How big was Alioramus?
Kurzanov (1976) estimated about 5-6 m for Alioramus remotus. Molina-Perez and Larramendi (2016) give about 5.5 m and 500 kg for A. remotus, and about 5 m and 385 kg for A. altai. Paul (1988) listed about 6 m and 700 kg. This page uses 5.5 m and 500 kg as facts-panel baselines and notes the range. Turn on the human figure to compare with a 1.8 m person.
What kind of dinosaur was Alioramus?
It is a tyrannosaurid theropod in the tribe Alioramini - a long-snouted branch separate from Tarbosaurus and Tyrannosaurus. Specimens show a slender build and distinctive nasal crests or bumps along the snout.
When and where did Alioramus live?
In Late Cretaceous rocks of the Nemegt Formation in Mongolia, about 72-66 million years ago. Sergei Kurzanov named Alioramus remotus in 1976; Brusatte and colleagues named A. altai in 2009 from a more complete skeleton.
Is the model scientifically accurate?
The proportions follow published figures, but the skin color and soft-tissue outline are an artistic reconstruction - fossils preserve bone, not soft tissue or color. This model is not a fossil-accurate skeleton. The length, weight, and age figures shown are real published values, with ranges cited where sources disagree.
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.
