I don’t keep in mind precisely which dinosaurs I noticed after I first visited Chicago’s Field Museum as a baby, however I’ll always remember the fun of seeing the large skeletons striding forth out of the previous. Since then, I’ve seen many different fossilized dinos at many different museums, and the fun stays the identical.
This challenge’s cowl story investigates the hovering reputation of museum-quality dinosaur fossils as collectibles, with intellectual public sale homes like Christie’s promoting off Tyrannosaurus rex skeletons as in the event that they’re items of artwork. As earth and local weather author Carolyn Gramling studies, Stan the T. rex, a skeleton found on personal land in South Dakota, bought for an eye-popping $31.8 million in 2020, and a T. rex cranium went for $6.1 million final December.
Stan disappeared after it was auctioned off. Last 12 months, it was revealed that the United Arab Emirates is the proprietor and intends to put Stan in a brand new pure historical past museum. The fossil commerce is nothing new, however most museums can’t compete at these value factors. And although many international locations regulate fossil gross sales, loopholes abound.
With every fossil that disappears from public view, science — and the general public — loses. Scientists concern that new finds might go straight to non-public house owners with out being correctly studied. With so few T. rex fossils unearthed, every specimen holds large scientific worth.
Fortunately for us dinophiles, museums do have T. rex skeletons on show and of their collections. The Field Museum homes Sue, whose $8.36 million buy in 1997 was underwritten by companies and tutorial establishments. The Smithsonian’s National Museum of Natural History in Washington, D.C., is dwelling to a T. rex found in Montana in 1988. Because the fossil was discovered on federal land, it prevented the public sale block and now chomps on an unfortunate Triceratops within the museum’s not too long ago renovated fossil corridor.
In this challenge, we additionally discover one other supply of frustration in science: Our restricted understanding of melancholy. The often-debilitating dysfunction impacts hundreds of thousands of individuals worldwide. But regardless of many years of effort, scientists nonetheless can’t describe the way it works or what causes it. The acquainted “chemical imbalance” concept doesn’t absolutely seize what’s occurring within the mind, not to mention the affect of exterior components like gender, race and tradition. How a person experiences melancholy additionally is determined by the place they stay and the way they expertise the world round them.
Researchers are looking for not solely a greater grasp on what’s taking place contained in the mind, but in addition how inner and exterior components work together. One barrier to transferring the science ahead is that completely different researchers depend on completely different definitions of melancholy and completely different strategies of assessing whether or not an individual is depressed. As neuroscience and senior author Laura Sanders notes, it’s like attempting to determine the science of temperature with out a thermometer.
It’s a unprecedented problem, and one which researchers might not clear up of their lifetimes. But I’m grateful that they’re attempting to find the roots of a illness that plagues so many.

The personal assortment and buy of fossil specimens has develop into more and more widespread over the previous a number of many years, as nationwide legal guidelines in lots of international locations have been modified to allow the gross sales of previously restricted fossil artifacts. This shift has definitely allowed fossil collectors to amass uncommon and even distinctive fossil specimens, nevertheless it’s value contemplating the potential penalties of this development.
The personal fossil market is basically unregulated, leaving many fossil fanatics with the troublesome process of distinguishing bona fide specimens from fakes or these of questionable provenance. This can symbolize a significant drawback, since scientifically necessary fossils with distinctive options, or these of particular provenance, could also be troublesome to authenticate in the event that they have been beforehand present in unapproved places.
Not solely can this lead collectors to be duped or to inadvertently break legal guidelines, however any data related to fossils misplaced within the course of can also be misplaced to scientific inquiry. Indeed, it’s important for correct authentication to have the ability to refer again to actual subject location, the geology of the situation, the age and stratigraphy of the specimen, and extra. When this data is misplaced – because it so typically is because of unlawful extraction and the personal market – it could actually develop into more and more troublesome to precisely authenticate later fossils.
Not solely does the potential for scientific fraud exist, however the potential for the unlawful trafficking of fossils can also be excessive. Fossil smuggling has develop into an growing drawback, notably when the origins of a fossil are unknown. With little to no authorized oversight, the personal fossil market can simply develop into a profitable avenue for fossil trafficking and smuggling.
The availability of personal fossil markets shouldn’t be discounted. However, you will need to weigh the potential penalties (together with shortly and unknowingly acquired pretend specimens, the lack of scientific data associated to acquisition and subject knowledge, and the specter of unlawful fossil buying and selling) earlier than getting into the market. As Stewart Wing, a Christian thinker, has mentioned: “The treasures could be there, however the hunt have to be carried out responsibly.”
