T he most complete and best-preserved Stegosaurus specimen of its size ever discovered is coming to auction at Sotheby’s New York.
Discovered in May 2022 on privately owned land in Moffat County, Colorado, near the aptly-named town of Dinosaur, the fossil—named “Apex”—was meticulously excavated by commercial paleontologist Jason Cooper, who embraced a philosophy of “minimal intervention.” Cooper and his team expertly highlighted Apex’s awe-inspiring natural beauty while preserving critical contextual details, including fossilized skin impressions and cervical ossicles.
Distinguished by its remarkable size, “Apex” is an outstanding exhibition-ready mounted skeleton, measuring approximately 11 feet tall and 27 feet long.
J oin Sotheby’s Cassandra Hatton, Global Head of Science and Popular Culture, as she travels across the U.S. to meet with Cooper to ensure that the documentation and sale of this extraordinary specimen are managed with the utmost care and transparency—from excavation to auction.
See it for yourself alongside other highlights from Geek Week, spanning Natural History and Space Exploration. The exhibition is currently on free and public exhibition at Sotheby’s New York City galleries from 10-15 July (10:00 AM-5:00 PM EDT).
