Stan the T-Rex Skeleton

Named for Stan Sacrison, who discovered his remains on the South Dakota side of the Hell Creek Formation, Stan the T-Rex is widely regarded as one of the most complete fossil skeletons of its kind. He was found in 1987, less than a century after humans learned of his kind's existence, and lived in the late Cretaceous period some 65 million years ago. Over 30,000 hours of labor were involved in unearthing and piecing together his remains for placement on a custom mount. Going up for auction on October 6th at Christie's in New York, this is considered a "once in a generation chance" to own such a rare scientific treasure.
