Quetzalcoatlus Size Comparison
Quetzalcoatlus 3D Viewer pairs published azhdarchid pterosaur figures with a 1.8 m person - wingspan about 10-11 m (panel baseline 10.5 m) and mass about 70-250 kg (panel baseline 200 kg) - so the scale gap stays readable at a glance. Quetzalcoatlus was a pterosaur, not a dinosaur.
Quetzalcoatlus published figures
The Quetzalcoatlus facts panel and this table use the same real published measures (mass spans about 70-250 kg with panel baseline 200 kg disclosed):
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Wingspan | about 10-11 m (panel baseline 10.5 m); Size vs human uses about 10.5 m | ~5.8x a person tip-to-tip at the 10.5 m scale figure |
| Height | about 2.5 m (panel silhouette) | slightly above adult standing height |
| Weight | about 70-250 kg (panel baseline 200 kg) | near one human body mass at the panel baseline; range disclosed |
| When it lived | about 72-66 million years ago | Late Cretaceous; Texas Big Bend / Javelina Formation |
| Taxonomy note | azhdarchid pterosaur; named Lawson, 1975 | Quetzalcoatlus was a pterosaur - not a dinosaur; carnivore (likely small vertebrates) |
How the Quetzalcoatlus size-vs-human toggle stays honest
The Quetzalcoatlus model is drawn to a fixed on-screen wingspan so it fits the canvas; the Size vs human control then places a 1.8 m person at the true wingspan ratio to the catalogue about 10.5 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 Quetzalcoatlus
What a person would see is a Late Cretaceous azhdarchid pterosaur - not a dinosaur - whose panel wingspan is about 10.5 m - nearly six person-lengths tip to tip - with standing height about 2.5 m in the panel silhouette. Turn on Size vs human and orbit beside a wing to feel how the span compares to you.
What the Quetzalcoatlus size numbers are not
What these size numbers are not is a single tight mass census: mass stays in the published about 70-250 kg range with only the panel baseline 200 kg disclosed - the viewer does not claim one mass outside that range. Soft-tissue color in the viewer is still an artistic reconstruction. This model is not a fossil-accurate skeleton. The pterosaur-not-dinosaur disclosure is noted in the facts panel but does not change these published size figures. For the control walkthrough see how to view Quetzalcoatlus in 3D.
