Drag to rotate the Saurosuchus, scroll or pinch to zoom, and click a body part - the head, the body, or the tail - to read what fossils tell us about it. The panel beside the model carries the real figures.
Saurosuchus was a rauisuchian archosaur, not a dinosaur - the apex predator of the Ischigualasto Formation ecosystem in what is now Argentina, sharing its habitat with some of the earliest known dinosaurs. Its deep, boxy skull converges strikingly with large theropod dinosaurs even though the two lineages evolved separately. This model shows a cautious quadrupedal reconstruction with legs tucked more under the body than a sprawled crocodilian.
The colors and skin here are an artistic reconstruction; fossils preserve bone, not soft tissue or color. This model is not a fossil-accurate skeleton. The measurements in the panel follow published estimate ranges because sources disagree.
Saurosuchus 3D Viewer
This page renders a Saurosuchus as a 3D model you can spin in the browser - drag to rotate, scroll or pinch to zoom, toggle a person beside it for scale, and click the head, the body, or the tail to read a fact about that part.
Saurosuchus galilei was a rauisuchian pseudosuchian, a crocodile-line archosaur that lived in the Late Triassic, roughly 231 to 225 million years ago, in what is now northwestern Argentina. It was not a dinosaur - it belongs to a separate branch of archosaurs - but fossil evidence points to it being the apex predator of its ecosystem, sharing the Ischigualasto Formation with some of the earliest known dinosaurs, including Herrerasaurus and Eoraptor. Osvaldo A. Reig described it in 1959 from a skull found by Galileo J. Scaglia and Leocadio Soria in 1957.
Published length estimates span about 5.5 to 7 m, with some studies suggesting up to 9 m because no complete skeleton has been found; mass is estimated at about 590 kg, following the three-dimensional model published by Henderson and Snively in 2003. Its skull measured up to about 58.6 cm and shows a strong resemblance to the skulls of much later, unrelated theropod dinosaurs - a case of convergent evolution rather than shared ancestry. This page uses about 7 m and about 590 kg as its panel baseline and shows the wider ranges here because sources disagree.
| Measure | Figure |

| Length | about 5.5-7 m (panel baseline about 7 m; some estimates up to 9 m) |
| Weight | about 590 kg (Henderson and Snively, 2003) |
| When it lived | about 231-225 million years ago (Late Triassic) |
| Group | Rauisuchian pseudosuchian, not a dinosaur |
| Diet | Carnivore - likely apex predator of its ecosystem |
Everything runs on your device with WebGL, so the model works without an account and without sending anything to a server. The skin tone and pattern are an artistic reconstruction, because fossils do not preserve color or soft tissue; this model is not a fossil-accurate skeleton. Saurosuchus shares its rauisuchian branch with the already-shipped Postosuchus 3D Viewer - both are Triassic crocodile-line predators, not dinosaurs, but Saurosuchus lived earlier, in South America, and is the larger of the two.
Frequently Asked Questions
Was Saurosuchus a dinosaur?
No. Saurosuchus was a rauisuchian pseudosuchian - a crocodile-line archosaur from the Late Triassic - not a dinosaur. This viewer includes it because it was the apex predator of an ecosystem that also contained some of the earliest known dinosaurs.
How big was Saurosuchus?
Published estimates span about 5.5 to 7 m long, with some studies suggesting up to 9 m because no complete skeleton is known. Mass is estimated at about 590 kg, following a three-dimensional model published by Henderson and Snively in 2003. Turn on the human figure to compare with a person.
Did Saurosuchus live alongside dinosaurs?
Yes. Its fossils come from the Ischigualasto Formation in Argentina, which also preserves some of the earliest known dinosaurs, including Herrerasaurus and Eoraptor. Saurosuchus was almost certainly the apex predator of that ecosystem, well before dinosaurs became dominant.
Is the model scientifically accurate?
The proportions follow the same cautious quadrupedal rauisuchian reconstruction as this site's Postosuchus viewer - a deep boxy skull, a raised trunk, and legs tucked more under the body than a sprawled crocodilian - but the skin color and pattern are an artistic reconstruction. Fossils preserve bone, not soft tissue or color. This model is not a fossil-accurate skeleton.
Where and when was Saurosuchus found?
Its holotype skull was found in 1957 by Galileo J. Scaglia and Leocadio Soria in the Ischigualasto Formation near San Juan, Argentina, and described by Osvaldo A. Reig in 1959. It lived roughly 231 to 225 million years ago, in the Late Triassic.
Do I need to install anything to view it?
No. The model renders in your browser with WebGL - no app, no account, and nothing about your visit is sent to a server. The 3D engine loads once and is then cached. When available, a free-licensed glTF model may swap in after first paint.
