Ichthyovenator Size Comparison
Ichthyovenator 3D Viewer pairs Early Cretaceous Laos figures with a 1.8 m person - length about 8.5-10.5 m (Size vs human uses 9.5 m), mass about 2-2.4 tonnes - so the sinusoidal-sail spinosaurid scale gap stays readable.
Ichthyovenator published figures
The facts panel and this table disclose published ranges; Size vs human uses 9.5 m:
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 8.5-10.5 m (Paul 2016 about 8.5 m; Molina-Perez and Larramendi about 10.5 m); Size vs human uses 9.5 m | ~5.3x a person end-to-end at the 9.5 m scale figure |
| Standing height | about 2.5-3 m at the hips (proportionate / published hip-height estimates) | ~1.4-1.7x adult standing height at the hips |
| Weight | about 2-2.4 tonnes | shown as a cross-source range, not one settled midpoint |
| When it lived | ~125-113 million years ago (Early Cretaceous), Gres Superieurs Formation, Laos; carnivore (often fish); Allain et al. 2012; sinusoidal sail | distinct from Spinosaurus (Southeast Asia vs North Africa) |
How the Ichthyovenator size-vs-human toggle stays honest
The Ichthyovenator 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 (9.5 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 8.5-10.5 m, so the toggle picks one clear scale inside that disclosed range.
What a person would see beside an Ichthyovenator
On Ichthyovenator Size Comparison, What a person would see is an Early Cretaceous Laos spinosaurid - turn on the person in the viewer and orbit beside the sail to feel how the wave-like crest dips over the hips 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 a North African sail comparison see the Spinosaurus 3D Viewer.
What the Ichthyovenator size numbers are not
What these size numbers are not is a claim of one precise length or weight: the size comparison discloses the about 8.5-10.5 m / 2-2.4 tonnes ranges and uses 9.5 m only for the Size vs human scale; it does not invent soft-tissue or sail-membrane color accuracy, and this is not a win/lose game.
