A Triceratops that spent nearly 30 years on public display is headed to auction, with a $4.5 million to $5.5 million estimate. Nicknamed Trey, it was found near Lusk, Wyoming in 1993 and stood at the Wyoming Dinosaur Center from its 1995 opening until 2023, when it moved to Singapore after a private sale. Joopiter, the online auction platform founded by Pharrell Williams, will accept bids March 17-31. The sale follows headline auctions, including a $44.6 million stegosaurus in 2024 and a more than $30 million young dinosaur at Sotheby’s, that have reset prices and prompted debate over access, provenance and regulation.

The auction of Trey is a rare case of a museum-displayed skeleton entering the open market. Joopiter, the online auction platform founded by Pharrell Williams, is handling the sale. Joopiter put Trey’s pre-auction estimate at $4.5 million to $5.5 million. The platform says the fossil is available for private viewings in Singapore through the end of March.

Trey is 17 feet long. Palaeontologists Lee Campbell and the late Allen Graffham found it in 1993. The specimen greeted visitors at the Wyoming Dinosaur Center when the museum opened in 1995 and remained on loan there until 2023.

Why prices are jumping

High headline sales are changing expectations. In 2024 a stegosaurus, known as Apex, sold for $44.6 million. That eclipsed the previous record of $31.8 million paid for a Tyrannosaurus rex called Stan in 2020. At Sotheby’s, a rare young dinosaur with a $4 million to $6 million estimate ended up selling for more than $30 million including fees. Those transactions helped push fossils into the frame as alternative assets.

Caitlin Donovan, Joopiter’s global head of sales, says buyers are moving away from traditional categories like old master paintings. She told Joopiter that buyers want items with cultural resonance. Paleontologist Andre LuJan, who worked with Joopiter to prepare Trey for sale, said the specimen has a cultural link to the public and has inspired visitors and young scientists.

How the fossil market operates

The fossil business mixes fieldwork, private brokering and auction houses. Finding large, intact skeletons is costly and risky. Salomon Aaron, director at London’s David Aaron gallery who brokers fossils, notes discovery is labor-intensive and financially uncertain. That scarcity helps drive prices when a high-profile specimen appears at auction.

Commercial palaeontologists and dealers often play a central role. They excavate, prepare and document finds before selling them to collectors, institutions or through private transactions. Trey’s path from field discovery to museum display to private sale illustrates that chain.

Mastheads

Provenance and authentication are increasingly central. Auction houses and sellers now demand detailed documentation. Independent specialists commonly verify authenticity and condition. Salomon Aaron says the market lacked the depth of the art market but is developing stricter provenance practices as high prices raise scrutiny.

Who pays and what they get

Buyers include private collectors, galleries and investors. Some seek display pieces for homes or corporate lobbies. Others see fossils as alternative investments that have posted oversized headline returns in recent auctions. The specimens that command the highest sums are usually complete, scientifically interesting and visually arresting.

That combination explains interest in Trey. Beyond its scientific age of more than 66 million years, the skeleton has public recognition from two decades at the Wyoming museum. That recognition adds value, LuJan said, because the fossil connects with people in ways many private finds do not.

Concerns from scientists and dealers

The market boom has stirred pushback from parts of the scientific community. Paleontologists warn that when rare specimens move into private ownership, scientists can lose access to material needed for research. Museum officials face higher price competition for acquisitions and sometimes lose out to deep-pocketed private buyers.

Ethical questions follow. Salomon Aaron highlights the tension between private collecting and public display. He says the market has lacked the advisory and research infrastructure that art markets rely on. That gap can make pricing and provenance harder to assess and could affect long-term value.

Legal frameworks also vary by country. National rules shape how specimens are collected, sold and exported. Source documents note that provenance rules now require extensive paperwork, and that verification by independent experts is standard for high-value sales.

Auction houses and online platforms are adapting. Joopiter is positioning itself as a venue for culturally resonant collectibles, with celebrity backing and digital reach. Sellers are using global viewings and online bidding to widen the pool of potential buyers. That can raise final prices by bringing more bidders into the same room, even if that room is virtual.

Sellers are also investing more in documentation and pre-sale research. Auction catalogs now emphasize provenance, scientific significance and restoration history. Independent vetting helps reassure buyers and governments who enforce export rules.

The market is still narrower than major art markets. Salomon Aaron describes it as underdeveloped compared with established art trading. That shows up as fewer pricing comps and less advisory infrastructure. It can also mean greater volatility when a single headline sale resets expectations.

Regulation and export rules can affect liquidity. A specimen moving from one country to another may face permits or legal hurdles. Those hurdles can delay sales and add cost, which buyers factor into bids.
