Carnotaurus Size Comparison
Carnotaurus 3D Viewer pairs published Late Cretaceous abelisaurid figures with a 1.8 m person on screen - length about 7.5-8 m for the single known skeleton (other estimates from that holotype up to about 9 m; Size vs human uses about 7.8 m) and weight about 1.3-2.1 tonnes - so the scale gap stays readable at a glance.
Carnotaurus published figures
The Carnotaurus facts panel and this table disclose published ranges rather than one invented single number; the Size vs human control uses about 7.8 m as the length scale ratio:
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 7.5-8 m core estimate for the single known skeleton; other estimates from that holotype up to about 9 m; Size vs human uses about 7.8 m | ~4.3x a person end-to-end at the 7.8 m scale figure |
| Weight | about 1.3-2.1 tonnes | sources disagree by study - shown as a range |
| Signature anatomy | paired thick conical brow horns; forelimbs even more reduced than a Tyrannosaurus rex's; holotype preserves bumpy non-overlapping scale skin impressions (no feather evidence); tail and lower legs never recovered - inferred from close abelisaurid relatives | horns sit above eye height on the head mesh; vestigial arms stay tucked |
| When it lived | 69-66 million years ago | Late Cretaceous (Maastrichtian); La Colonia Formation, Chubut Province, Argentina; Jose Bonaparte named Carnotaurus sastrei in 1985 from a single skeleton |
How the Carnotaurus size-vs-human toggle stays honest
The Carnotaurus 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 (about 7.8 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 7.5-8 m with other estimates from the same skeleton up to about 9 m, so the toggle picks one clear scale inside that disclosed range.
What a person would see beside a Carnotaurus
What a person would see is a bipedal theropod with a pair of thick brow horns and extremely reduced forelimbs - turn on the person in the viewer and orbit beside a hind leg to feel how the horizontal-back posture and raised counterweight tail sit relative to the scale figure. Skin color is an artistic reconstruction; the holotype's real skin impressions show a bumpy scale mosaic, but the tail and lower legs in any full-body view (including this one) are inferred because those parts were never recovered.
What the Carnotaurus size numbers are not
What these size numbers are not is a claim of one precise length or weight: the Carnotaurus size comparison discloses the literature ranges and uses about 7.8 m only for the Size vs human scale; it does not invent a hip-height figure the skill does not carry, does not claim the tail and lower legs are known from the holotype, no free-licensed Carnotaurus glTF is re-hosted yet so the viewer stays procedural with feats.horns, and this is not a win/lose game.

Other dinosaurs to compare
Other dinosaurs in the collection make useful size comparisons too: Carnotaurus is a Late Cretaceous horned abelisaurid, so for a Late Cretaceous apex predator see the Tyrannosaurus rex 3D Viewer, or for a Late Jurassic Morrison Formation theropod see the Allosaurus 3D Viewer.
