And so, the hammer came down and bidding ended on a remarkable Stegosaurus fossil skeleton that had been offered for sale at the auction house Sotheby’s (New York). The Stegosaurus specimen, nicknamed “Apex” sold for a whopping $44.6 million USD (£34.5 million GBP). This is a world record amount for a dinosaur fossil. It had an estimated value of between $4 million and $6 million USD. However, as the bidding started this was soon exceeded.
Seven bidders wanted this Stegosaurus, and they were prepared to pay big bucks to get it. After fifteen minutes of frantic excitement lot thirteen was sold. Unsurprisingly, given the sums involved, the Stegosaurus fossil skeleton was purchased by an anonymous bidder. The buyer is believed to be a billionaire hedge fund owner (Kenneth Griffin).

“Apex” A Stunning Stegosaurus Fossil Skeleton
“Apex” was discovered on privately owned land in Moffat County, Colorado. The land is owned by a commercial palaeontologist called Jason Cooper. It is ironic, that the dig site was close to the small town of Dinosaur. The material, representing a single animal, consists of 254 fossil bones. This represents nearly eighty percent of the entire skeleton. The estimated number of bones in a Stegosaurus skeleton is 319, give or take the odd chevron.
Not only is it one of the most complete large dinosaur skeletons discovered, the bones bear witness to some remarkable pathology that helps tell the tale of this iconic Late Jurassic herbivore. The mounted skeleton measures over 8.2 metres long.

Auction House and Commercial Palaeontologist Co-operating Closely
Cassandra Hatton, Sotheby’s Global Head of Science & Popular Culture worked closely with Jason Cooper from the day of discovery onwards. The fossils were carefully documented and excavated. The material was prepared and mounted and at each stage the highest standards of transparency were adhered to. The aim being to preserve as much information about the fossils as possible. Skin impressions were noted and three, tiny ossicles representing throat armour were carefully extracted from the Morrison Formation matrix. These also ended up as part of the Stegosaurus lot.
This is the first time an auction house has been so intimately involved with a dinosaur skeleton.
Cassandra stated:
“This sale has been years in the making, and at every turn, we have worked closely with Jason Cooper, from the moment of its discovery in Dinosaur, Colorado, to its sale in New York. I am thrilled that such an important specimen has now taken its place in history, some 150 million years since it roamed the planet. This remarkable result underscores our unwavering commitment to preserving these ancient treasures.”
Following the sale, the anonymous buyer is believed to have remarked:
“Apex was born in America and is going to stay in America!”
An Amazing Specimen
The fossil was preserved in hard sandstone and the black colour is typical of Morrison Formation specimens. The fossils represent a fully-grown, robust adult and the fossilisation is described as “superb”, with little or no distortion. Along with the skin impressions, fragile cervical plates and elements of the pebbly throat armour have been preserved. Some fossil bones indicate the presence of arthritis. This suggests “Apex” lived to an old age. There are no signs of combat injuries or trauma on the bones. In addition, there is no evidence of post-mortem scavenging by theropod dinosaurs.
A spokesperson from Everything Dinosaur commented that it was hoped that this remarkable Stegosaurus fossil skeleton would be made available to science for further study.
The spokesperson added:
“Commercial palaeontologists play an important role as they excavate specimens that could have been lost to science through erosion and weathering. To excavate, clean and prepare such a remarkable specimen would have probably cost hundreds of thousands of dollars. Whilst we understand the importance of financial gain in these situations, and we suspect a portion of the money will be reinvested in further field work and research, hopefully, this specimen will be made available to the scientific community for further analysis and study.”
Sotheby’s Natural History Auction
The auction featured numerous amazing fossil specimens as well as meteorites, minerals, gogottes and for the first time, Palaeolithic tools including tools made by Neanderthals. The Neanderthal tools sold for $22,800 USD, much higher than the pre-auction estimate. A large iridescent ammonite fetched an eye-watering $72,000 USD.
Other fossils in the auction included mass mortality trilobite fossils from Morocco, Megalodon otodus teeth, fossil eurypterids from New York and beautiful fossilised fish. The natural history themed auction also featured meteorites and rare minerals including a large lapiz lazuli tower from Afghanistan.
The auction also included numerous dinosaur fossils such as a Tyrannosaurus rex femur, two T. rex teeth and an Edmontosaurus (E. annectens) skull.

Auctions of fossils and other rare objects can be controversial. For example, Everything Dinosaur has previously reported upon the seizure of a Tarbosaurus specimen after evidence emerged that it had been illegally smuggled out of Mongolia.

Sadly, there is a lot of illegal fossil collecting taking place. Many of these specimens are sold on the black market and find their way into Europe and America. However, the authorities in many countries are cracking down on this illegal trade and some perpetrators have been jailed.

The spokesperson from Everything Dinosaur commented:
“It is worrying to read of other rare items being offered for auction, particularly the Palaeolithic tools. The large sums of money these lots are sold for could incentivise unscrupulous parties to exploit archaeological sites as well as fossil quarries. Let us hope that sales such as this leads to closer regulation and greater co-operation between countries.”
