Two years ago hedge‑fund titan Ken Griffin shelled out nearly $45 million for a stegosaurus skeleton, setting a record for the most expensive fossil ever sold at auction. The sale signaled a shift as dinosaur remains increasingly attract billionaire collectors rather than public museums.

Bloomberg’s Odd Lots podcast dives into the opaque world of private fossil trading, questioning why priceless paleontological pieces evade scholarly institutions. Host interviews Salomon Aaron, director at London‑based David Aaron gallery, which doubles as a brokerage for high‑value dinosaur bones, to map the market’s parallels with fine‑art and antiquities.

The segment reveals that wealthy buyers treat fossils as status symbols, leveraging tax‑advantaged structures and private auctions to conceal provenance. Dealers like Aaron negotiate deals behind closed doors, often bundling specimens with certification papers that mirror art‑market practices, complicating efforts by scientists to trace specimens’ origins.

As the trade swells, museums risk losing access to specimens that could illuminate evolutionary history, while regulators grapple with loopholes that allow high‑net‑worth individuals to amass natural‑heritage assets. The episode underscores a growing tension between private wealth and public science, forcing a reevaluation of how cultural patrimony is defined.
