Elasmosaurus Skeleton and Skull Cast

The Legend That Launched the Bone Wars Now in Your Collection

No marine reptile captures imagination quite like Elasmosaurus platyurus. With its impossibly long neck and striking silhouette, this ancient ocean predator reigned supreme in the Western Interior Seaway and sparked one of the most dramatic rivalries in scientific history.

This is the famous “Cope Elasmosaur,” the very specimen that ignited the legendary Bone Wars of the 1870s. When paleontologist E.D. Cope mistakenly mounted the skull on the wrong end of the skeleton, his rival O.C. Marsh publicly humiliated him, setting off a fierce scientific feud that would shape American paleontology for decades.

Now, you can own a museum-quality replica of the fossil that started it all.

The Cast

Our Elasmosaurus platyurus skeleton and skull casts are based on authentic specimens and produced using museum-grade polyresin and molding techniques. Each cast captures the extraordinary detail of this predator’s build, from the sleek, torpedo-like body to the over 70 neck vertebrae that make up more than half its total body length.

Available as a full articulated skeleton or standalone skull, this cast is a dramatic centerpiece for collectors, institutions, and marine life enthusiasts.
