S otheby’s Natural History department, founded by Vice Chairman and Worldwide Head Cassandra Hatton, leads the global market for museum‑quality fossils and scientific specimens, building on its historic 1997 sale of “Sue” the T. rex. The team works directly with commercial paleontologists to offer fully documented, expertly prepared fossils of the highest caliber. Our flagship Natural History auction takes place in New York each July during Geek Week, alongside select single‑lot sales and occasional international offerings in Hong Kong and London. In addition to auctions, the department handles private sales for museums, institutions and collectors worldwide, making Sotheby’s the premier destination for exceptional Natural History specimens today.
