A rare dinosaur skeleton nicknamed “Jodi” has sold for $47.3 million at Sotheby’s in New York, making it the second-most-expensive dinosaur fossil ever sold at auction. The specimen belongs to Nanotyrannus, a small tyrannosaur relative that lived approximately 67 million years ago. Its final price dramatically exceeded Sotheby’s presale estimate of $6 million to $9 million.
The October 27, 2026, auction attracted six bidders competing online and by telephone over roughly 12 minutes. The buyer’s identity remains undisclosed. The sale highlights the growing market for exceptionally rare prehistoric fossils while renewing a debate among paleontologists over private ownership, public access and the scientific value of important dinosaur discoveries.

What Is the Nanotyrannus Skeleton Jodi?
Jodi is a remarkably preserved skeleton of Nanotyrannus, a predatory dinosaur related to Tyrannosaurus rex. Measuring approximately 19.6 feet from nose to tail and standing around 9.6 feet tall on its mounting structure, the specimen is considerably smaller than an adult T. rex.
The skeleton contains approximately 191 fossil bone elements and features a nearly complete skull. Sotheby’s described it as an exceptionally rare specimen, with only three substantial Nanotyrannus skeletons known to science.
The dinosaur lived during the Late Cretaceous period, roughly 67 million years ago, in an environment that also supported T. rex and other prehistoric animals. Although smaller than its famous relative, Nanotyrannus had distinctive anatomical characteristics, including relatively longer forelimbs, larger hand claws and slender teeth.
The fossil was discovered in 2019 by rancher Jodi Pierson on her land in Montana’s Hell Creek Formation. Commercial paleontologist Clayton Phipps subsequently led the excavation.
The specimen was named after Pierson, whose discovery helped bring an unusually rare dinosaur to the fossil market.
Why Did the Dinosaur Sell for $47.3 Million?
The final price was several times higher than the auction house’s upper estimate of $9 million. A bidding contest involving six prospective buyers lasted approximately 12 minutes before the fossil was sold.
Several factors help explain the result.
Exceptional rarity: Only a handful of substantial Nanotyrannus skeletons are known. The limited supply of comparable specimens makes each major fossil auction unusual.
Scientific significance: The specimen entered the market after recent research strengthened the case for recognizing Nanotyrannus as a distinct genus rather than a juvenile T. rex. That scientific development increased interest in the animal’s identity and evolutionary significance.
Display appeal: Jodi is a large, mounted skeleton that can serve as a centerpiece for a private collection, exhibition or museum-style display.
Competition among wealthy buyers: Major fossil auctions attract collectors seeking rare natural-history objects. When several bidders compete for a unique specimen, the final price can exceed the original estimate substantially.
The auction result does not mean every dinosaur fossil is worth millions. Value depends on rarity, preservation, scientific importance, legal ownership, provenance and demand among collectors.
Jodi Versus Other Record-Breaking Dinosaur Fossils
Jodi’s sale comes amid a series of exceptionally expensive dinosaur auctions.
| Dinosaur fossil | Sale price | Auction year |
|---|---|---|
| T. rex skeleton Gus | $50.1 million | 2026 |
| Nanotyrannus skeleton Jodi | $47.3 million | 2026 |
| Stegosaurus skeleton Apex | $44.6 million | 2024 |

Jodi narrowly missed the record established by Gus, the T. rex skeleton sold earlier in 2026. It nevertheless achieved one of the highest auction prices ever recorded for a dinosaur fossil.
The comparison also illustrates the commercial appeal of rare prehistoric specimens beyond the most famous dinosaur species. Nanotyrannus may be less familiar to the general public than T. rex, but its scarcity and scientific story helped attract substantial interest.
The Scientific Debate Over Nanotyrannus
For decades, paleontologists debated whether Nanotyrannus was a distinct dinosaur or simply a young T. rex that had not yet reached adult size.
The distinction matters because juvenile animals can differ substantially from adults in body proportions, skull structure and other anatomical features. If Nanotyrannus were merely a juvenile T. rex, its fossils would provide information about the growth of a familiar species. If it were a separate genus, the evidence would point to a more diverse ecosystem of large predatory dinosaurs.
Research published in 2025 strengthened the argument that Nanotyrannus was a distinct genus. Scientists examined skeletal development and anatomical differences that were inconsistent with the idea that the specimens were simply immature T. rex individuals.
The new evidence has helped shift scientific opinion, although the classification has a long and contested history. Jodi’s significance therefore extends beyond its auction price: it is part of an ongoing effort to understand dinosaur diversity near the end of the Cretaceous period.
Why Scientists Are Concerned About Private Fossil Sales
The sale has reignited a long-running disagreement over whether scientifically important fossils should be sold to private collectors.
Researchers argue that fossils can provide evidence about anatomy, evolution, growth, disease and prehistoric ecosystems. When a major specimen enters a private collection, researchers may have limited opportunities to examine it, conduct further studies or compare it with other fossils.
Public museums and research institutions can preserve specimens, make them available for scientific investigation and display them for educational purposes. Scientists concerned about private sales argue that these benefits can be lost if access depends on an owner’s willingness to cooperate.
Commercial fossil hunters and sellers offer a different perspective. They argue that private investment can finance expensive excavations and help recover fossils that might otherwise remain undiscovered or be lost through erosion.
In the United States, fossils found on private land can generally be privately owned and sold, subject to applicable laws and valid ownership rights. The rules differ for federal and other public lands.
The debate is therefore not simply about whether fossil sales should exist. It is about how to balance property rights, commercial incentives, scientific research and public access to important natural-history discoveries.
The Bigger Picture
Jodi’s $47.3 million sale demonstrates the financial value that exceptionally rare fossils can command in the global collectibles market. Its price reflects a combination of scarcity, preservation, scientific interest and competition among wealthy buyers. The sale also shows that major fossil auctions are no longer limited to the most recognizable dinosaur species.
However, the scientific importance of a fossil cannot be measured by its auction price alone. A specimen’s greatest long-term contribution may come from the research it enables and the knowledge it provides about prehistoric life. Whether Jodi remains in a private collection or eventually becomes accessible to a public institution will influence how easily researchers and visitors can engage with the discovery.
