Nearly 1,000 skeletal pieces make up Gus the T. Rex. Thomas Heitkamp and his excavation expert team spent more than five years in South Dakota, digging 60–70 feet into the ground to uncover the 67-million-year-old dinosaur now on view at #SothebysNewYork. Listen as Sotheby's Cassandra Hatton and the crew describe the grueling yet rewarding process and watch the short documentary at the link in our bio. Plan your visit to 945 Madison Ave to see Gus before the Natural History Auction on 14 July. The Summer Season is presented in partnership with sothebysrealty.
