A 66-million-year-old Triceratops skeleton, nicknamed Trey, sold for $5.55 million at the online auction platform Joopiter.

2025 has been a landmark year for dinosaur fossils in the art world, marked by high-profile sales, seizures, and ethical controversies. In November, a pair of Allosaurus fossils and a Stegosaurus skeleton worth £12 million ($15.6 million) were seized by the UK's National Crime Agency from Binghai Su, a Chinese national linked to a major money-laundering case in Singapore. The fossils had been purchased at Christie's Jurassic Icons auction in 2024. Meanwhile, Sotheby's sold a juvenile Ceratosaurus fossil for $30.5 million in July, far exceeding its $6 million estimate, and Phillips entered the dinosaur market for the first time, selling a juvenile Triceratops skeleton for $5.4 million in November. The most expensive dinosaur fossil ever, a Stegosaurus named Apex bought by hedge fund titan Kenneth Griffin for $44.6 million in 2024, was loaned to the American Museum of Natural History.
A rare juvenile Ceratosaurus fossil sold for $30.5 million at Sotheby's New York, far exceeding its $6 million presale estimate after a six-minute bidding war. The 154-159 million-year-old specimen, discovered in 1996 at Wyoming's Bone Cabin Quarry, contains 139 original bone elements and stands over 6 feet tall. Sotheby's stated the buyer plans to loan the fossil to an institution.
