Tyrannosaurus rex fossil Stan becomes the most expensive dinosaur ever sold

The Tyrannosaurus rex fossil known as Stan set a record when it sold for $31.8 million, making it the most expensive dinosaur ever sold at the time. The nearly complete T. rex, discovered in South Dakota in 1987 and excavated in the early 1990s, was offered at auction in New York in October 2020. Its sale drew major attention from scientists and collectors, and it later became part of museum exhibition plans.
