Drag to rotate the Moropus, scroll or pinch to zoom, and click a body part - the head, a foreleg, or the tail - to read what fossils tell us about it. The panel beside the model carries the real figures.
Moropus was a giant Ice Age mammal, not a dinosaur - turn on the human figure to see how it towered over a person on four legs, let alone when it rose onto its hind legs to reach tree branches.
The colors and fur pattern here are an artistic reconstruction; fossils preserve bone, not soft tissue or color. The body proportions follow the fossil skeleton, but the measurements in the panel are the ones actually published.
Moropus 3D Viewer
This page renders a Moropus as a 3D model you can spin in the browser - drag to rotate, scroll or pinch to zoom, toggle a 1.8 m person beside it for scale, and click a body region to read a fact.
Moropus was a clawed chalicothere mammal, not a dinosaur. It lived in the Miocene, about 20.4-13.6 million years ago, across North America. Marsh named the genus in 1877. Large species such as M. elatus stood about 2.4 m at the shoulder; length about 3-3.5 m; one specimen is estimated at about 1179 kg.

Frequently Asked Questions
How big was Moropus?
Large species such as M. elatus stood about 2.4 m at the shoulder. Length is about 3-3.5 m. One specimen is estimated near 1179 kg. Turn on the human figure for scale.
Is Moropus a dinosaur?
No. It was a Miocene chalicothere - an odd-toed ungulate mammal with large forelimb claws used for browsing. This cluster also hosts other non-dinosaurs when readers search for them here.
When and where did it live?
Miocene North America, about 20.4-13.6 million years ago. Marsh named the genus in 1877.
What does the name mean?
Moropus means slow foot, from Greek. It refers to early ideas about its gait; the large claws are the distinctive feature readers notice first.
Is the model scientifically accurate?
Size follows published figures with ranges, but skin color and soft tissue are artistic. This is not a fossil-accurate skeleton.
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. When available, a free-licensed glTF model may swap in after first paint.
