Despite mostly being owned by museums and private institutions, Christie’s offers a chance for wealthy collectors to own a 67-million-year-old T-Rex skeleton as part of its upcoming October Evening Sale of 20th Century Art.

The skeleton named “Stan,” after an amateur paleontologist Stan Sacrison who discovered it in 1987 is considered to be one of the few completely assembled skeletons of its kind, unearthed at Hell Creek Formation — located between South Dakota, Wyoming, and Montana.

Stan is currently on display at Christie’s flagship location on 49th Street in New York City. It will remain on view until October 21. The 13 feet high and 40 feet wide ancient specimen is expected to fetch between $6-8 million. The auction will commence on October 6, visit Christie’s website to learn more.
