Spinosaurus Size Comparison
Spinosaurus 3D Viewer pairs published sail-backed figures with a 1.8 m person on screen - length about 14 m, hip height about 2.1 m, and weight about 7.4 tonnes (7400 kg) - so the theropod scale gap stays readable at a glance.
Spinosaurus published figures
The Spinosaurus facts panel and this table use the same real published measures (a range where sources disagree):
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 14 m (earlier estimates sometimes up to about 15 m; NHM / Sereno et al. 2022) | ~7.8x a person end-to-end at the 14 m figure |
| Hip height | about 2.1 m | ~1.2x adult standing height; model uses this for Size vs human |
| Weight | about 7.4 tonnes / 7400 kg | about 7.4 metric tons on the facts panel |
| Sail spines | elongated neural spines up to about 1.65 m | dorsal sail over the back on the procedural model |
| When it lived | 99-94 million years ago | Late Cretaceous; fossils from Egypt (1912 finds; named by Stromer, 1915) |
How the Spinosaurus size-vs-human toggle stays honest
The Spinosaurus 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-to-hip-height ratio for the about 14 m figure (hip height about 2.1 m). 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 Spinosaurus
At about 2.1 m at the hip, a Spinosaurus hip line sits a little above a 1.8 m person's head. From snout to tail the animal spans about 14 m - turn on the person in the viewer and orbit beside a hind leg to feel how the long snout and dorsal sail tower past the scale figure.
What the Spinosaurus size numbers are not
The Spinosaurus size comparison uses published estimates with an honest length range; skin and sail color are an artistic reconstruction, and a fully aquatic lifestyle is not settled science on the viewer page.
