Gus the T. rex Could Break Dinosaur Auction Record, Sparking Fossil Ownership Debate

Gus, one of the most complete T. rex fossils ever found in South Dakota, goes to Sotheby’s with a $30 million pre-sale value and a $19 million starting bid, potentially becoming the most expensive dinosaur ever sold. The auction reignites a debate over whether scientifically important fossils should stay in museums or be privately owned, since private specimens are harder for researchers to access and many journals won’t publish work on them. Excavation and recovery spanned years, and while collectors help fund finds, scientists stress public accessibility and rigorous study as essential for understanding dinosaur biology and our past.
