Big John (dinosaur)
Auctioned Triceratops fossil / From Wikipedia, the free encyclopedia
Big John is a fossilized Triceratops horridus skeleton discovered in South Dakota's Hell Creek geological formation in 2014. It is the largest known Triceratops skeleton, according to the team that assembled the fossil. Big John's 2021 auction price of €6.6 million (US$7.7 million) made it the most expensive Triceratops skeleton; its high price signaled increasing demand for dinosaur fossils among private collectors and prompted discussion about the drawbacks of private fossil ownership for scientific research.
