Coelophysis Size Comparison


Coelophysis 3D Viewer pairs published theropod figures with a 1.8 m person - length about 2.5 m, mass about 20 kg - so the scale gap stays readable at a glance.


Coelophysis published figures

Compare four published Coelophysis size figures using the four points in this diagram.
Length 2.5 m, height 0.8 m, mass 20 kg, lived 228-201 Ma.

The Coelophysis facts panel and this table use the same real published measures (a range where sources disagree):

MeasureFigureVs a 1.8 m person
Lengthabout 2-3 m (panel baseline 2.5 m)~1.4x a person end-to-end; Size vs human uses 2.5 m
Heightabout 0.8 m (panel silhouette)below adult standing height
Weightabout 15-25 kg (panel baseline 20 kg)similar to a large dog, lighter than a human
When it livedabout 228-201 million years agoLate Triassic; Chinle Formation / Ghost Ranch, New Mexico
Fossil noteNamed Cope, 1889early bipedal theropod; Ghost Ranch bone beds are a major sample

How the Coelophysis size-vs-human toggle stays honest

The Coelophysis 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 about 2.5 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 Coelophysis

What a person would see is a slender early bipedal theropod whose panel length is about 2.5 m - a little longer than one body length of a 1.8 m person laid end to end - with hips about 0.8 m high in the panel silhouette. Turn on Size vs human and orbit beside the snout to feel how a small Late Triassic carnivore compares to you.


What the Coelophysis size numbers are not

What these size numbers are not is a single tight mass census: mass stays the disclosed about 15-25 kg range with panel baseline 20 kg. Soft-tissue color in the viewer is still an artistic reconstruction. For the control walkthrough see how to view Coelophysis in 3D.
