Gryponyx Size Comparison
Gryponyx 3D Viewer pairs published sauropodomorph figures with a 1.8 m person - length about 5 m, mass poorly constrained - so the scale gap stays readable at a glance.
Gryponyx published figures
The Gryponyx facts panel and this table use the same real published measures (mass is poorly constrained; one secondary estimate about 485 kg):
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 5 m (panel baseline 5 m) | ~2.8x a person end-to-end; Size vs human uses 5 m |
| Height | about 1.6-2.0 m at hips (panel baseline 1.8 m) | near adult standing height at the panel baseline |
| Weight | mass poorly constrained; one secondary estimate about 485 kg | several times a human body mass at that estimate; not a tight census |
| When it lived | about 201-190 million years ago | Early Jurassic; Upper Elliot Formation, South Africa |
| Fossil note | Named Broom, 1911 | hooked-claw sauropodomorph herbivore; historically synonymized with Massospondylus; Vasconcelos and Yates argued distinctive |
How the Gryponyx size-vs-human toggle stays honest
The Gryponyx 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 to the catalogue about 5 m panel baseline. Tap Size vs human under the canvas to show or hide the scale figure - the comparison is proportional, not a decorative sticker.
What a person would see beside a Gryponyx
What a person would see is a hooked-claw Early Jurassic sauropodomorph whose panel length is about 5 m - nearly three body lengths of a 1.8 m person laid end to end - with hips about 1.8 m high in the panel baseline. Turn on Size vs human and orbit beside the snout to feel how an Upper Elliot Formation herbivore compares to you.
What the Gryponyx size numbers are not
What these size numbers are not is a single tight mass census: mass stays poorly constrained with only one secondary estimate about 485 kg disclosed - the viewer does not claim mass is tightly constrained from fossils. Soft-tissue color in the viewer is still an artistic reconstruction. This model is not a fossil-accurate skeleton. The Massospondylus synonymy history is noted in the facts panel but does not change these published size figures. For the control walkthrough see how to view Gryponyx in 3D.

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
