Avaceratops Size Comparison
Avaceratops 3D Viewer pairs Late Campanian Montana figures with a 1.8 m person - length about 2.3-4.2 m (Size vs human uses 4.2 m), mass about 1 tonne - so one of the smaller known ceratopsids stays readable beside a human scale.
Avaceratops published figures
The facts panel and this table disclose published figures; Size vs human uses 4.2 m:
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 2.3 m (holotype; maturity debated) to about 4.2 m (referred skull MOR 692 adult estimate); Size vs human uses 4.2 m | ~2.3x a person end-to-end at the 4.2 m scale figure |
| Standing height | about 1.5-1.8 m at the hips for a larger individual (panel 1.6 m) | ~0.8-1.0x adult standing height at the hips |
| Weight | about 1 tonne for a roughly 4 m animal (Paul 2010); panel 1000 kg | shown as a published mid-size figure, not a settled single mass |
| When it lived | ~77 million years ago (Late Cretaceous Campanian), Judith River Formation, Montana; herbivore; Dodson 1986; A. lammersi | compare larger ceratopsids via Triceratops / Albertaceratops viewers |
How the Avaceratops size-vs-human toggle stays honest
The Avaceratops 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 referred-adult length ratio used by the viewer (4.2 m). Tap Size vs human under the canvas to show or hide the scale figure - the comparison is proportional, not a decorative sticker. The holotype about 2.3 m stays disclosed in the facts panel and does not claim a full-grown adult at that length.
What a person would see beside an Avaceratops
On Avaceratops Size Comparison, What a person would see is a Late Campanian Montana ceratopsid with a solid frill - turn on the person in the viewer and orbit beside the hip or frill to feel how the smaller ceratopsid 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. For larger ceratopsids see the Triceratops 3D Viewer and the Albertaceratops 3D Viewer.
What the Avaceratops size numbers are not
What these size numbers are not is a claim that the holotype was a full-grown adult at 2.3 m: the size comparison discloses about 2.3-4.2 m / about 1 tonne figures and uses 4.2 m for the Size vs human scale; it does not invent soft-tissue color accuracy, and this is not a win/lose game.
