Dinosaur fossil sets $30.5M auction record after fierce bidding war

A rare juvenile Ceratosaurus fossil has fetched an astonishing $30.5 million at Sotheby's New York, selling for more than five times its high presale estimate of $6 million after a fierce six-minute bidding war, making it the third most valuable dinosaur ever sold at auction.

Record-Breaking $30.5 Million Sale

The bidding battle for the juvenile Ceratosaurus was nothing short of spectacular, beginning with a high advance offer of $6 million before rapidly escalating as six determined bidders drove the price skyward over six intense minutes. Bids initially increased in $500,000 increments before jumping to $1 million steps, ultimately reaching a hammer price of $26 million, which climbed to the final $30.5 million figure after fees and costs. The audience erupted in applause when auctioneer Phyllis Kao gaveled the sale closed. While the buyer's identity remains undisclosed, Sotheby's has revealed that the purchaser plans to loan this exceptional specimen to an institution, ensuring this scientific treasure will be available for public viewing and study.news.artnet+4

Fierce Six-Minute Bidding War

The auction room crackled with tension as the bidding for the juvenile Ceratosaurus rapidly intensified beyond all expectations. What began as a $4-6 million estimate transformed into an electrifying competition that captivated everyone present at Sotheby's New York "Geek Week" auction. The six-minute duel saw phone, online, and in-room bidders aggressively vying for ownership of this prehistoric treasure, with auctioneer Phyllis Kao masterfully orchestrating the escalating offers.news.artnet+2

Unlike the Mars meteorite auction held during the same event—which progressed slowly enough that the auctioneer needed to coax more offers and decrease minimum bid increments—the Ceratosaurus sparked immediate and enthusiastic interest. The extraordinary nature of the specimen—being one of only four known Ceratosaurus nasicornis skeletons and the only juvenile example ever discovered—clearly resonated with collectors of natural history. This frenzied bidding battle ultimately propelled the fossil to join the ranks of the most valuable dinosaurs ever sold, cementing its place in auction history alongside last year's record-holder, "APEX" the Stegosaurus, which fetched $44.6 million.mentalfloss+3

Juvenile Ceratosaurus Specimen Rarity

The juvenile Ceratosaurus that commanded such a staggering price is truly exceptional in the fossil world. Discovered in 1996 near the historic Bone Cabin Quarry in Wyoming, this 150-million-year-old specimen from the Late Jurassic period stands approximately 6 feet 3 inches tall and 10 feet 8 inches long. What makes this fossil particularly valuable is its remarkable state of preservation, featuring 139 original bone elements, including an impressively intact skull composed of 57 individual fossil components that houses a complete set of 43 fossilized teeth.news.artnet+2

This specimen represents the only known juvenile of its kind among just four Ceratosaurus fossils ever discovered. The rarity is further enhanced by its completeness—unlike many partial dinosaur finds requiring significant reconstruction, this specimen offers paleontologists an unprecedented opportunity to study the juvenile stage of this horned predator. Prior to the auction, the fossil was owned by Brock Sisson, founder of the commercial paleontology company Fossilogic, who had a personal connection to the specimen after caring for it as a teenager while it was housed at the Museum of Ancient Life in Utah. The skeleton was mounted for the first time in its history specifically for this auction, allowing bidders to appreciate its scientific significance and natural beauty in full display.stupiddope+4
