Baryonyx Size Comparison
Baryonyx 3D Viewer pairs published Early Cretaceous figures with a 1.8 m person on screen - length about 7.5 m on the 2010 revision (historical to about 9.5-10 m), hip about 2-2.5 m, and weight about 1200 kg - so the scale gap stays readable at a glance.
Baryonyx published figures
The Baryonyx facts panel and this table disclose published ranges rather than one invented single number; the Size vs human control uses 7.5 m as the length scale ratio:
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 7.5 m (2010 Cuff & Rayfield body-mass revision); earlier 1986-1997 descriptions up to about 9.5-10 m; Size vs human uses 7.5 m | ~4.2x a person end-to-end at the 7.5 m scale figure |
| Hip height | commonly about 2 to 2.5 m across sources (cross-source range, not one NHM figure) | taller than a standing adult; roughly chest-to-head height on a tall person |
| Weight | about 1.2 tonnes / 1200 kg (2010 study); older estimates about 1.7-2.7 tonnes | shown as a method-attributed range, not one settled point |
| Thumb claw | about 31 cm curved claw (Natural History Museum holotype description) - Greek barys + onyx, "heavy claw" | disclosed in facts panel and prose; not a separate click target; arm mesh uses small generic claws |
| Vs Spinosaurus | Baryonyx: England, ~130-125 Mya, no back sail, stomach-content fish + juvenile Iguanodon evidence; Spinosaurus: North Africa, ~99-94 Mya, sail present, fish diet mainly snout/isotopes | same theropod archetype and conical teeth in this collection; different genus, geography, era, and diet evidence |
| When it lived | ~130-125 million years ago (Barremian), Early Cretaceous England; named Charig & Milner 1986; found 1983 by William J. Walker; ~70% skeleton at NHM London | type locality Surrey clay pit; not a fully aquatic lifestyle claim |
How the Baryonyx size-vs-human toggle stays honest
The Baryonyx 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 (7.5 m from the 2010 body-mass revision). 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 7.5-10 m historically, so the toggle picks one clear scale inside that disclosed range.
What a person would see beside a Baryonyx
What a person would see is a crocodile-snouted, fish-eating theropod without a back sail - turn on the person in the viewer and orbit beside a hind leg to feel how the body sits relative to the scale figure. The thumb claw's about 31 cm length is a factual disclosure in the facts panel, not a separately tagged click target. Skin color is an artistic reconstruction; the model is procedural with no free-licensed Baryonyx glTF re-hosted yet.
What the Baryonyx size numbers are not
What these size numbers are not is a claim of one precise length or weight: the Baryonyx size comparison discloses the 2010 figures (7.5 m / 1200 kg) alongside the wider 1986-1997 historical range (up to about 9.5-10 m / 2.7 t) and uses 7.5 m only for the Size vs human scale; it does not claim Baryonyx was fully aquatic, does not invent a dedicated click-the-claw interaction, no free-licensed Baryonyx glTF is re-hosted yet so the viewer stays procedural, and this is not a win/lose game.

Other dinosaurs to compare
Other dinosaurs in the collection make useful size comparisons too: for the sail-backed spinosaurid sibling see the Spinosaurus 3D Viewer, or for another large theropod see the Allosaurus 3D Viewer.
