Record-Breaking $44.6 Million Sale of Complete Stegosaurus Fossil 'Apex'

A record-breaking Stegosaurus fossil, named 'Apex', was sold for $44.6 million at an auction held by Sotheby's on July 18, 2024. The sale price surpassed the pre-sale estimate of $4 million to $6 million and set a new record for dinosaur fossils.

Discovered in Moffat County, Colorado, near Dinosaur town by commercial paleontologist Jason Cooper in 2022, Apex is one of the most complete Stegosaurus skeletons ever found. It measures 11 feet tall and nearly 27 feet long from nose to tail and has approximately 75% of its bones present.

The large, robust adult specimen showed no signs of combat-related injuries or postmortem scavenging, indicating that it lived to an advanced age. There is also evidence suggesting that Apex had arthritis.

Hedge fund billionaire Ken Griffin was the successful bidder for Apex and plans to explore loaning the specimen to a U.S. institution for display.

Apex's sale follows in the footsteps of other high-profile dinosaur fossil sales, such as 'Stan', a Tyrannosaurus rex sold for $31.8 million in 2020 and 'Sue', a T. rex sold for $8.4 million in 1997.

Despite the excitement surrounding Apex's sale, some paleontologists argue that fossils like this should be kept in museums or research centers instead of being sold to private bidders.

Sotheby's auction house handled the sale and reported that there were seven bidders during the live auction. The buyer, who chose to remain anonymous, said: 'Apex was born in America and is going to stay in America.'

    The article contains an appeal to authority when it quotes Cassandra Hatton, Sotheby's Global Head of Science & Popular Culture, stating 'Apex lived up to its name today, inspiring bidders globally to become the most valuable fossil ever sold at auction.' This statement is not a logical fallacy in and of itself but becomes one when taken out of context and used as evidence for the value or significance of the fossil. However, since this is not a central argument in the article, it does not significantly impact the overall score.

    The author, Nadeem Badshah, presents factual information without any clear logical fallacies. However, there are a few instances of inflammatory rhetoric and appeals to authority. The use of phrases like 'most valuable fossil sold at auction' and 'inspiring bidders globally' contribute to an inflated sense of importance for the event.

    The author makes several statements in the article that are not fallacious, but there are a few instances of inflammatory rhetoric and an appeal to authority. The author uses the phrase 'dino-mite deal' to describe the sale of the stegosaurus skeleton, which is an example of inflammatory rhetoric intended to elicit an emotional response from the reader. Additionally, when describing Ken Griffin as a 'billionaire investor,' 'founder of Citadel hedge fund,' and 'one of the top 200 art collectors in the world with a collection valued at $1 billion,' the author is appealing to his authority and wealth to establish credibility. However, these fallacies do not significantly detract from the overall quality of the article.
