Comparacao de tamanho do Brontosaurus


Brontosaurus 3D Viewer combina figuras publicadas do Jurassico Superior com uma pessoa de 1.8 m - comprimento cerca de 21-23 m para B. excelsus (Size vs human usa 22 m), massa cerca de 15-20 toneladas - para a escala do sauropode ficar legivel de imediato.


Comparacao de tamanho do Brontosaurus

Compare four published Brontosaurus size figures using the four points in this diagram.
Length 22 m scale, 15-20 t mass, 5-6 m shoulder, 2015 reinstatement.

Published ranges with Size vs human at 22 m:

MeasureFigureVs a 1.8 m person
Lengthabout 21-23 m (B. excelsus); smaller species about 19 m; Size vs human uses 22 m~12.2x a person end-to-end at the 22 m scale figure
Shoulder heightabout 5-6 m at the shoulder for a large adult~2.8-3.3x adult standing height
Weightabout 15-20 tonnes commonly cited for B. excelsus; some published averages highershown as a cross-source range, not one settled midpoint
When it lived~156-146 million years ago (Late Jurassic), Morrison Formation; Marsh 1879; Tschopp et al. 2015distinct from shipped Apatosaurus after 2015

Honest scale

Size vs human places a 1.8 m person at the 22 m length ratio - proportional, not a sticker. Optional CC0 glTF may load after first paint.
