Vintage Chicago Tribune: Sue the T. rex's journey to the Field Museum

Vintage Chicago Tribune: Sue the T. rex's journey to the Field Museum

Chicago Tribune15-05-2025
Our city — the one of 'Big Shoulders' — has always sought out the massive. Chicago has been home to the tallest building (when it was known as Sears Tower), the largest convention center (McCormick Place) in North America, and even one of the world's largest wastewater treatment plants (Stickney Water Reclamation Plant which, OK, is in Cicero, just outside the city limits).
The opportunity to increase the city's stature once again materialized in October 1997. That's when the largest, most complete Tyrannosaurus rex skeleton became available at an auction hosted by Sotheby's. But bringing the fossil lovingly named after its discoverer to Chicago wouldn't have been possible without the combination of Sue Hendrickson and a flat tire.
As the Field Museum celebrates 25 years since the debut of Sue, here's a look back at how the T. rex made its way from the Black Hills of South Dakota to Chicago.
The vehicle of a dinosaur-hunting crew planning to leave a site in western South Dakota at the end of an expedition was found to have a flat tire. While others went into town to make the repair, Sue Hendrickson, a member of that crew, decided to have a look in an area the expedition had not searched. It was a good choice.
While examining a cliff's side, she discovered a Tyrannosaurus rex specimen — the largest, most complete and best preserved T. rex found to that date.
The dinosaur skeleton — which was estimated to be 90% complete — became known as Sue not because of its sex (undetermined) but after its finder.
Peter Larson, whose Black Hills Institute of Geological Research Inc., excavated the tyrannosaur, paid Maurice Williams, a member of the Cheyenne River Sioux tribe on whose land the fossil was found, $5,000.
The fossil was seized by federal authorities who claimed it was illegally removed from Williams' ranch, which was held in trust by the government. The Black Hills Institute was charged with violation of the U.S. Antiquities Act, theft of U.S. governmental property and theft of Native American tribal property.
Long before Sue's discovery, Peter Larson and his brother Neal had built Black Hills Institute on a reputation for highly skilled fossil preparations and exhibit mountings, selling them to a variety of private collectors and public museums, including the Field Museum.
When Hendrickson found Sue on Williams' land, the Larson brothers thought the extraordinary fossil would make a dream come true. They were going to build a nonprofit museum in Hill City, their hometown, drawing tourists from nearby Mount Rushmore.
Instead, the legal battles Sue sparked nearly bankrupted them.
The U.S. attorney's office in South Dakota, setting out to prove that the Larsons had illegally taken Sue and other fossils from federal lands, spent years and millions of dollars investigating the institute, raiding the company and carting off fossils and business records on several occasions.
In the resulting six-week trial, however, out of 146 felony charges, the jury convicted Peter Larson on two charges of failing to declare several thousand dollars he had carried with him on two business trips outside the U.S.
The 8th U.S. Circuit Court of Appeals ruled that Sue's fossil bones technically were a constituent of the soil, part of the land, and belonged to the landowner, Williams. The Supreme Court let that decision stand.
Peter Larson, whose success as a private fossil-hunter had raised the hackles of many academic paleontologists, was sent to prison on federal charges that many South Dakotans came to regard as an abuse of prosecutorial power
'I wouldn't wish that on my worst enemy,' Larson later told the Tribune. 'This was so hard on my wife, worse for her than for me. On every visiting day she traveled hundreds of miles and was there for me. But the whole ordeal drained her, and when I got out (on Dec. 8, 1998), she decided she didn't want to be married anymore. That was the hardest thing, to lose her.'
A judge awarded ownership of Sue to Williams, and the government, acting as his trustee, decided the best way to serve his interests was to auction the skeleton.
The bidding for Sue started at $500,000 and rose by $100,000 increments, quickly breaking into the millions as bidders on the floor and on phones competed for what auctioneer Redden called 'a world treasure.'
The crowd in the sales room gasped as the bidding broke through $5 million and kept climbing.
At the $7 million mark, most of the would-be buyers dropped out and tension mounted in the room as the time between bids lengthened. Finally, after several warnings, auctioneer David Redden knocked Sue down at $7.6 million — for a total of $8.36 million.
The auction took little more than eight minutes.
In the end, bidding came down to the Field Museum, the J.I. Kislack Foundation of Miami, the North Carolina State Museum of Natural Sciences, and the Dallas Museum of Natural History. Redden said a private buyer was also in the final bidding but refused to identify him.
Later, McCarter said he was never confident that Field would come away the winner.
'I was very nervous' as the bidding progressed, he said.
He declined to reveal how high the museum had been willing to go to buy Sue.
At the time, it was the highest price paid for a fossil (until a stegosaurus nicknamed 'Apex' grabbed that title in 2024). Williams received $7.6 million of the money the museum paid for Sue.
But Williams never planned to visit the fossil that once was buried on his land.
'Everybody is knowledgeable about the amount of money (Sue) brought into our family,' Williams, father of four grown children, said in a 2000 telephone interview with the Tribune. 'What we got out of the thing, we're handling it pretty well. Some of the children have used it for education and whatever.
'People here don't talk anymore about that thing.'
The Black Hills Institute claimed it had a trademark on the name Sue and that the name couldn't be used without permission.
'The trademark we have on Sue is exactly the same as … Mickey Mouse,' said Marion Zenker, marketing coordinator for the private fossil-hunting institute. 'Walt Disney didn't own the mouse, but he still owned the name.'
On April 15, 1998, the dinosaur formerly known as Sue then became formally be known as Sue. The news came as a disappointment to the thousands of kids who entered a contest to give the dinosaur a new name after legal disputes over licensing of the name Sue erupted. But museum officials conceded that lawyers advised that the contest-winning name — 'Dakota' — had the potential to cause legal problems as well, given that it was already used for several products.
Hendrickson — who did not have a high school diploma — received her first university credentials in the form of an honorary doctorate of humane letters from the University of Illinois Chicago.
The professional fossil hunter and self-taught archaeologist and paleontologist with a namesake T. rex at the Field Museum came to paleontology by way of an early career diving for sunken treasure and collecting fish specimens in the Caribbean. She was a voracious reader as a child in Munster, and decided against a formal university education after talking things over with the head of marine biology at the University of Washington.
Hendrickson had always been a hard worker, her mother said, and hoped that her success and the recognition she received serves as inspiration for other people who pursue their ambitions without the benefit of a college degree.
Sue — whose chocolate-brown skeleton took 12 people 30,000 hours to remove from rock — debuted in Stanley Field Hall (the lobby inside the Field Museum).
'Sue has a number of features never before observed in the other T. rex skeletons,' Tribune reporter William Mullen wrote. 'The new information underscores what scientists for the last several years have been postulating: that dinosaurs are closely related to birds.'
'Evolving Planet' opened, thanks to a donation by Ken Griffin, founder and CEO of Citadel. The $17 million permanent exhibit used video, interactive displays, paintings and lots and lots of fossils to chronicle the evolution of life on Earth over 4 billion years.
Sue's new smaller but much more dramatic digs on the museum's second floor opened.
The new home also incorporated changes in the presentation of the skeleton — including a much fuller chest thanks to the mounting of formerly separated gastralia, or 'belly ribs' — which were all carefully detailed on accompanying labels that help tell a bigger story.
'We wanted to use Sue as a vehicle to inform the public that science is never done,' said museum CEO Richard Lariviere. 'You're always understanding.'

I'm a physicist who studies fossils, and I recently discovered preserved blood vessels in the world's largest T. rex

Despite the fact that much of the current research in paleontology focuses on trying to find traces of organic remains in fossils, dinosaur DNA has unfortunately never been recovered. A lot of what we know about dinosaurs comes from preserved bones and teeth that are dug out of the ground. These hard tissues alone, however, are limited in the information they provide. Soft tissues are extremely rare in the fossil record, but can help provide a much more life-like reconstruction of ancient life. This includes things like muscles and ligaments, pigments or even skin (like scales or feathers), which contain detailed information on how dinosaurs lived and what they looked like. Another interesting soft tissue that can be found in bones are blood vessels. My research team and I discovered blood vessels preserved in a Tyrannosaurus rex fossil, and our findings were recently published in Scientific Reports. As an undergraduate physics student at the University of Regina, I joined a research team using particle accelerators to study fossils. There, I first discovered blood vessels in a bone from a T. rex using advanced 3D models. It's been nearly six years since that moment; I am now working on my PhD where I use my background in physics to advance analysis techniques in fossil research. An extraordinary specimen The vessels were found in a remarkable T. rex specimen nicknamed Scotty. Held in the Royal Saskatchewan Museum's collection in Canada, Scotty is the largest T. rex ever unearthed. The fossil also remains one of the most complete specimens of T. rex. Scotty appeared to have had a rough life 66 million years ago; many of the recovered bones appeared to have injuries, possibly due to a fight with another dinosaur, or disease. One bone in particular, a section of rib, features a large partially healed fracture. In general, after bones experience a traumatic event like a fracture, there is a huge increase in the activity of blood vessels in the affected area as part of the healing process. We believe this is what was found in Scotty's rib: an extensive network of mineralized vessels that we were able to examine using reconstructed 3D models. Revolutionizing paleontology research When analyzing fossil bones, there are two main challenges. The first is how to examine the interior of the bones without damaging the fossil. And second, the bones are very large and can be quite dense due to the fossilization process, where minerals replace and fill in original organic materials. At first, we thought we could perform an computed topography (CT) scan of the bone, similar to what is used for medical purposes, which allows imaging of bones without damaging them. While this solves the first problem, the second problem means that a conventional medical CT machine is not nearly powerful enough to penetrate the dense bone. For our examination, we used synchrotron light, special high-intensity x-rays. These are produced at select particle accelerator labs, and allow us to investigate microstructures such as blood vessels in the bone with ease. Synchrotron x-rays can also be useful for chemical analysis. We found the vessels were preserved as iron-rich mineralized casts, a common form of fossilization, but in two distinct layers. This layering is due to the complicated environmental history that led to the exceptional preservation seen in Scotty's rib. Written in blood vessels By analyzing blood vessels produced by an incompletely healed fracture, we can hopefully learn how T. rex healed, helping speculation on how Scotty was able to survive after sustaining injuries. This could lead to evolutionary information comparing the vessel structures seen in Scotty to other dinosaur species, as well as modern relatives to dinosaurs like birds. The results may also help future fossil exploration by guiding scientists to target bones that show signs of injury or disease, potentially increasing the chances of discovering more vessels or other types of preserved soft tissues. With cross-disciplinary research and novel applications of advanced technologies, there is so much potential to recreate the past lives of dinosaurs like never before.

When is the next full moon? Sturgeon Moon will rise over Mississippi soon in August 2025

The August full moon will rise over Mississippi soon. But stargazers have other astronomical events to look forward to this month. Showy fireballs and shooting stars will be visible at night over Mississippi until late August. Three meteor showers are happening now. The Perseid is the most famous of the trio. According to the American Meteor Society, it runs from about July 17 to Aug. 23. The alpha Capricornids are still in progress and will be active through about Aug. 12, according to the American Meteor Society. The Delta Aquariid Meteor Shower will also be visible from July 18 through around Aug. 12. Falling stars can be visible from evening through dawn, meaning you don't have to stay up late for this stargazing, though the best times are between midnight and dawn. Can the full moon keep you from seeing the celestial show? Here's what to know about the August full moon and when you can try to get the best view of the meteor showers over Mississippi. When is the August full moon? The full moon in August, called the "Sturgeon Moon," will be on Aug. 9, 2025. Peak illumination will be 2:55 a.m. CT, according to Farmer's Almanac. Moonrise in Jackson will be at 7:48 p.m. CT, on Aug. 8, according to That'll be shortly after sunset around 7:51 p.m. Why is it called the Sturgeon Moon? According to Farmer's Almanac, it's called the Sturgeon Moon because lake sturgeon were plentiful this time of year. The fish were an important food for Native American tribes. Other names for this moon include: Black Cherries Moon Corn Is in the Silk Moon Corn Moon Dry Moon Feather Shedding Moon Grain Moon Green Corn Moon Hot Moon Hunger Moon Lightning Moon Plum Moon More: When to watch Perseid meteor shower light up the sky tonight in Mississippi What nights will have the most meteors in August? The Perseids will peak around Aug. 12-13, according to the American Meteor Society. Peak periods for these showers were around July 29-30, but they're still putting on a show. It's just not the maximum number of meteors you might see. What are the best nights to see shooting stars in August? The worst nights for viewing meteor showers will be in the days surrounding the full moon. NASA released an article explaining that the full moon will be 84% full on the peak nights of the Perseids. You still might see a few bright meteors before dawn, but overall visibility will be low on the nights when the most will be shooting across the sky. The new moon is Aug. 23, so the darker nights as the moon wanes will be your best bet for a night sky dark enough to see the end of the Perseid. What are the names of other full moons throughout the year? Other popular nicknames for monthly full moons, according to the Old Farmer's Almanac, include: Wolf Moon (January) Snow Moon (February) Worm Moon (March) Pink Moon (April) Flower Moon (May) Strawberry Moon (June) Sturgeon Moon (August) Corn Moon (September) Hunter's Moon (October) Beaver Moon (November) Cold Moon (December) Why do we see moon phases? There are four lunar phases based on the Earth's position between the sun and the moon. A full moon means the entire visible side of the moon facing Earth is reflecting sunlight. When less of the moon gets light, it's dark (a new moon) or waxing or waning. Full moons normally happen 29.5 days apart and once a month. Rarely are there two full moons in a single month. It's called a "blue moon," and the next one will be on May 31, 2026. Contributing: Mary Walrath-Holdridge Bonnie Bolden is the Deep South Connect reporter for Mississippi with Gannett/USA Today.

When is August's full moon? What to know about Aug. 9 sturgeon moon.

The full moon will be visible just before the popular Perseid meteor shower reaches its peak around Aug. 12 to 13. The August 2025 full moon is coming to a sky near you. August's sturgeon moon will reach peak illumination on Saturday, Aug. 9, 2025, at 3:55 a.m. EDT. The full moon should be visible as it rises in the sky on the evening of Friday, Aug. 8, weather permitting, of course. It's known as the sturgeon moon thanks to the giant fish that were once plentiful this time of the year in the waters of the northeastern United States. The full moon will be visible just before the popular Perseid meteor shower reaches its peak around Aug. 12 to 13. Unfortunately for meteor viewers, the bright full moon could actually interfere with meteor shower viewing, astronomers said. According to a description of the meteor showers on "this year's spectacle comes with one major caveat: moonlight. The 80% illuminated waning gibbous moon will rise a few hours before midnight on Aug. 12 and remain high above the southern horizon until dawn, washing out all but the brightest meteors." Why is it called the Sturgeon moon? Full moon names are traditionally rooted in Native American culture or have Colonial American influences, according to the Farmer's Almanac. According to the almanac, the name sturgeon moon comes from the giant lake sturgeon of the Great Lakes and Lake Champlain; this native freshwater fish was readily caught during this part of summer and an important food staple for Native Americans who lived in the region. "At one time, the lake sturgeon was quite abundant in late summer, though they are rarer today," the Almanac said. As for the fish themselves, these prehistoric-looking fish have been traced back to around 136 million years ago, and many people call them 'living fossils.' What are some other names for August's full moon? Alternative names for the August full moon refer to seasonal crops and more. Some of these names include: Is there a supermoon in August 2025? No, there is no supermoon in August. The first supermoon of the year typically occurs in the later months, and this year it will be in October.
