Gorgosaurus Size Comparison
Gorgosaurus 3D Viewer pairs published Late Cretaceous Alberta figures with a 1.8 m person on screen - length about 8-9 m (Size vs human uses 8.5 m), mass about 2-3 tonnes - so the albertosaurine scale gap stays readable at a glance.
Gorgosaurus published figures
The Gorgosaurus facts panel and this table disclose published ranges rather than one invented single number; the Size vs human control uses 8.5 m as the length scale ratio:
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 8-9 m; Size vs human uses 8.5 m | ~4.7x a person end-to-end at the 8.5 m scale figure |
| Standing height | about 3 m at the hips for a large adult | ~1.7x adult standing height |
| Weight | about 2-3 tonnes | shown as a cross-source range, not one settled midpoint |
| When it lived | ~76.6-75.1 million years ago (Late Cretaceous), Alberta Dinosaur Park Formation; carnivore; Lambe 1914; albertosaurine - closer in size to Albertosaurus than to T. rex | smaller/slenderer than Tyrannosaurus rex |
How the Gorgosaurus size-vs-human toggle stays honest
The Gorgosaurus model is drawn to a fixed on-screen length so it fits the canvas; the Size vs human control then places a 1.8 m person at the true length ratio used by the viewer (8.5 m). Tap Size vs human under the canvas to show or hide the scale figure - the comparison is proportional, not a decorative sticker. Published length still spans about 8-9 m, so the toggle picks one clear scale inside that disclosed range.
What a person would see beside a Gorgosaurus
On Gorgosaurus Size Comparison, What a person would see is a Late Cretaceous Alberta albertosaurine - turn on the person in the viewer and orbit beside a hind leg to feel how the bipedal theropod posture sits relative to the scale figure. A license-clean CC-BY-SA 4.0 glTF may swap in after first paint; soft-tissue color remains an artistic choice if the model load fails. This model is not a fossil-accurate skeleton.
What the Gorgosaurus size numbers are not
What these size numbers are not is a claim of one precise length or weight: the Gorgosaurus size comparison discloses the about 8-9 m / 2-3 tonnes ranges and uses 8.5 m only for the Size vs human scale; it does not invent soft-tissue color accuracy, and this is not a win/lose game.

Other dinosaurs to compare
Other dinosaurs in the collection make useful size comparisons too: for the larger later tyrannosaurid see the Tyrannosaurus rex 3D Viewer.
