Pentaceratops Size Comparison
Pentaceratops 3D Viewer pairs published figures for a small Late Cretaceous European theropod with a 1.8 m person - length panel baseline 6 m and mass panel baseline 2.5 t - with published length, skull, and mass ranges disclosed separately.
Pentaceratops published figures
The Pentaceratops facts panel and this table use the same real published measures (published length, skull, and mass ranges disclosed separately):
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 5.5-7 m commonly cited near 6 m (panel baseline 6 m); Size vs human uses 6 m | ~3.3x a person end-to-end at the 6 m scale figure |
| Skull length | about 2.16-2.3 m among genuine Pentaceratops specimens (panel baseline 2.3 m) | ~1.3x a person end-to-end for the skull alone |
| Weight | about 2.5-3 t commonly cited (panel baseline 2.5 t) | many times a human body mass at the panel baseline |
| When it lived | about 76-73 million years ago | Late Cretaceous (Campanian); San Juan Basin, New Mexico |
| Identity (disclosed) | Five-horned face - two brow horns, one nose horn, two cheek projections - plus huge frill; herbivore; Osborn 1923; does NOT cite OMNH 10165 Guinness skull (now Titanoceratops) | holotype AMNH 6325 collected by Charles H. Sternberg 1921-1922 |
How the Pentaceratops size-vs-human toggle stays honest
The Pentaceratops 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 6 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 Pentaceratops
What a person would see is a frilled ceratopsian whose panel length is 6 m - shorter than a 1.8 m person end-to-end - with skull length about 2.3 m in the panel silhouette. Turn on Size vs human and orbit beside a hind leg to feel how a Late Cretaceous herbivore with a huge frill compares to you.
What the Pentaceratops size numbers are not
What these size numbers are not is a blended composite: the panel headline figures (6 m / 2.3 m skull hip / 2.5 t) are never merged with the German juvenile range (about 0.7-0.9 m / 0.3-0.6 kg) or treated as if every specimen matched the French adult. Soft-tissue color in the viewer is still an artistic reconstruction. This model is not a fossil-accurate skeleton. For the control walkthrough see how to view Pentaceratops in 3D.
