So sanh kich thuoc Barosaurus
Barosaurus 3D Viewer pairs published figures with a 1.8 m person - panel 26 m, panel 17 t.
Published figures
Facts panel and table use the same published measures:
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 24-27 m (panel baseline 26 m); Size vs human uses 26 m | compare end-to-end at the 26 m scale figure |
| Mass | about 12-20 t (panel baseline 17 t) | many times a human body mass at the panel baseline |
| Height | about 4.8 m proportional standing height (panel baseline; no direct published standing-height figure) | proportional panel estimate |
| When it lived | about 150-145 Mya Late Jurassic; Morrison Formation | panel era 150-145 Ma |
| Neck vs Diplodocus | 16 cervical vertebrae vs 15; some cervicals up to 50 percent longer | proportionally longer neck, shorter tail |
| Source conflict (disclosed) | Older ~45 m / ~60 t estimates now generally attributed to Supersaurus, not Barosaurus | panel uses 26 m / 17 t within published range |
| Identity (disclosed) | Othniel Charles Marsh 1890; Morrison Formation; herbivore; Longer neck than Diplodocus (16 vs 15 cervicals) and shorter tail | long-necked diplodocid sauropod |
How Size vs human stays honest
Fixed on-screen length; Size vs human places 1.8 m person at true ratio to panel 26 m.
What you see beside Barosaurus
A long-necked diplodocid sauropod at panel 26 m beside a 1.8 m person. Turn on Size vs human and orbit.
What size numbers are not
Not a blended composite outside published ranges. Artistic color. does not use ~45 m / ~60 t Supersaurus-reattributed estimates as Barosaurus figures; does not assert rearing-to-15-m head height as a measured fact. See how-to and vs AR guides.
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.
