Drag to rotate the Gorgosaurus, scroll or pinch to zoom, and click a body part - the head, a tiny arm, or a leg - to read what fossils tell us about it. The panel beside the model carries the real figures.
Gorgosaurus was an Alberta tyrannosaurid about 8-9 m long - smaller and more slender than Tyrannosaurus rex. Adults are commonly cited near 2-3 tonnes.
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.
Gorgosaurus 3D Viewer
This page renders a Gorgosaurus 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 tiny arm, or a leg to read a fact about that part.
Gorgosaurus lived in the Late Cretaceous, about 76.6 to 75.1 million years ago, in Alberta (Dinosaur Park Formation). Adults are about 8-9 m long and about 2-3 tonnes - an albertosaurine tyrannosaurid, smaller and more slender than Tyrannosaurus rex and closer in size to Albertosaurus. Named by Lambe in 1914 (G. libratus).

Frequently Asked Questions
How big was Gorgosaurus?
Adults reached about 8-9 m in length and about 2-3 tonnes in mass. Turn on the human figure to judge the scale beside a 1.8 m person.
How is Gorgosaurus different from Tyrannosaurus rex?
Gorgosaurus was smaller and more slender, lived earlier in Alberta (about 76.6-75.1 Mya), and belongs to the albertosaurine branch with Albertosaurus. T. rex is a later, bulkier tyrannosaurine.
Where did Gorgosaurus live?
Most fossils come from the Dinosaur Park Formation in Alberta, Canada, from the middle Campanian of the Late Cretaceous.
Is the model scientifically accurate?
The body proportions follow published reconstructions, but the skin color and texture are an artistic reconstruction. Fossils preserve bone, not color. The figures shown are real published values with ranges where sources disagree.
When was Gorgosaurus named?
Lawrence Lambe named Gorgosaurus libratus in 1914 from Alberta material.
