A 67-million-year-old Tyrannosaurus rex fossil, known as "Gus," is set to be auctioned in New York with a pre-sale estimate of $30 million, potentially making it the most expensive fossil ever sold. The specimen's remarkable completeness, with 61% of its bones identified, and its condition, including evidence of healed fractures and a significant bite mark on the skull, offer scientists a rare glimpse into the life of the prehistoric predator.
However, the sale has ignited a debate within the scientific community regarding the implications of such valuable specimens entering private collections. Cassandra Hatton, involved in the auction, emphasized the need for the price to reflect the substantial investment, skill, and risk involved in recovering dinosaur fossils, noting that excavators often operate with limited personal funds.
"Gus is one of the largest and most complete T. rex ever found," Hatton stated, adding that she has been contacting museums globally to secure a public institution for the fossil. She believes that scientifically important specimens should be accessible to the public.
Despite the potential for wealthy individuals to acquire these fossils, a significant challenge arises for scientific research. Leading scientific journals generally do not accept studies conducted on specimens housed in private collections. The rationale, according to Professor Paul Maidment of the Natural History Museum, is that scientific inquiry requires the ability for researchers to revisit, verify, and build upon findings over time, which is hindered when a fossil is not readily accessible.
"What happens [if] that person gets bored of them, dies, gets divorced. And there have been many cases where specimens have been in private collections, and there's been a scientific description of them and [that has] gone in the skip," Professor Maidment explained. "So it's actually just not science anymore."
Historically, museums have relied on donations, bequests, and loans from private collectors and benefactors to build their collections. Kenneth Griffin, founder and CEO of Citadel, for example, loaned the Stegosaurus specimen "Apex" to the American Museum of Natural History after its purchase. However, the increasing market value of significant dinosaur fossils is driving them into private hands, raising concerns about the long-term implications for paleontological research and public access to scientific heritage.
