Discovery of Sue the T-Rex (Summer 1990)

• Black Hills Institute geological research crew searching South Dakota ranch for months
• Found Edmontosaurus bones, preparing to return to Hill City
• Truck got flat tire, spare flat, pump hose broken
• Paleontologist Sue Hendrickson stayed back to search while others went to Faith for repairs
• Discovered articulated dinosaur vertebrae visible in hillside
• 17-day excavation removed entire hillside by hand
• Found 250 bones, one of most complete T-Rex skeletons ever found
• Institute founder Peter Larson met rancher Morris Williams
• Williams agreed to $5,000 payment for fossil (according to Larson)

Legal Seizure and Ownership Dispute (1992)

• May 14, 1992: FBI agents and National Guardsmen seized Sue from Black Hills Institute
• Acting Attorney General Kevin Schafer led investigation, argued fossil was stolen
• Morris Williams didn't technically own land - member of Cheyenne River Sioux tribe
• Land held in trust by federal government, required Bureau of Indian Affairs and tribal approval
• Four entities claimed ownership: Black Hills Institute, Morris Williams, Cheyenne River Sioux tribe, US Federal Government
• Judge ruled fossil was fundamental component of land Williams didn't own
• US government property, but Williams allowed to auction with tax-free proceeds
• Devastating blow to Black Hills Institute
• Larson jailed 2 years for failure to declare cash on customs form

Sue's Auction and Sale

• Sue trucked to New York, displayed at Sotheby's Gallery
• Sold for $7.6 million record price to Chicago Field Museum
• Record-breaking price attributed to ironclad legal ownership by US government
• Buyer confidence in clear title without seizure risk

Global Shipwreck Treasure Hunting Industry

• Estimated 200,000-250,000 shipwrecks in popular databases
• UNESCO estimates 3 million global shipwrecks
• Estimated $60 billion in valuable metal sunk (likely low estimate)
• Only 5% of ocean explored, 20% of floor mapped
• Industry ranges from individual pirates to US publicly traded companies
• Three value sources: physical material for scrap, historical artifacts, gold/silver coinage

SS Central America Case Study (1986)

• Discovery led by ocean engineer Tommy Thompson
• Ship 160 miles/260 km off North Carolina coast, 7,000 ft/2,100 m deep
• $12 million funding from 160+ investors
• 39 insurance companies sued Columbus America Discovery Group
• 10-year legal battle, 3 tons of gold sat in Virginia warehouse
• Court awarded 92% to Thompson and investors after 12 years
• Thompson took money and went into hiding instead of paying investors

Odyssey Marine Exploration Spanish Dispute (2007)

• Salvaged $500 million silver/gold coins off Portuguese coast
• Spanish government sued, claimed coins from Nuestra Señora de las Mercedes (Spanish frigate sunk 1804)
• Spain won through Foreign Sovereign Immunities Act interpretation
• 5 years after salvage, Spanish authorities reclaimed treasure via C-130s
• Odyssey paid $1 million fine

Maritime Law Complexity

• International maritime law of salvage gives finder rights
• Sovereign state claims override salvage law
• Most accessible wrecks in countries' exclusive economic zones
• Warships with cannons remain state property
• Legal uncertainty has doomed companies like Columbus America Discovery Group

US Fossil Industry Geographic Concentration

• China, Mongolia, Argentina, Canada, US have best fossils
• Only US has flourishing industry due to unique laws:
  • Fossils belong to landowner
  • Owners can sell/export freely
• All 10 most valuable dinosaur fossils sold came from Wyoming, South Dakota, Montana
• These three states became global epicenter of industry

Discovery and Sale of Stan the T-Rex (1992-2020)

• Black Hills Institute found second T-Rex weeks after Sue's seizure
• Originally thought to be Triceratops found by Stan Sacrison 5 years earlier
• 190 bones found (vs Sue's 250), fantastic condition
• Private property with proper paperwork
• Stan replaced Sue as Hill City Museum centerpiece
• Institute owns intellectual property rights to Stan's shape
• Replica casts sold for $150,000 to museums worldwide (Houston Museum of Natural Science, DC's National Museum of Natural History, Tokyo's National Museum of Natural Sciences, Disney World)

Black Hills Institute Family Dispute

• Peter Larson majority owner, brother Neil owned 35% minority stake
• 2012: Peter forced Neil out, personal relationship fractured
• Court sided with Neil for shareholder rights violation
• Business couldn't afford cash buyout of Neil's shares
• Neil received Stan (estimated $6-8 million value), Peter got rest of Institute

Stan's Record-Breaking Auction (October 2020)

• Christie's New York showroom auction alongside Monet, Van Gogh, Picassos
• Sold to Abu Dhabi Natural History Museum for $31,847,500
• New inconceivable record for dinosaur fossil sale
• Demonstrated industry's explosive profit potential

Government Collaboration in Maritime Salvage

• SS Gairsoppa project (2010-2013)
• UK Department of Transport opened competitive tender
• Odyssey won exclusive salvage contract, 80% treasure rights
• Ship torpedoed by German U-boat in WWII
• 300 miles/480 km off Ireland coast, 15,000 ft/4,700 m deep
• Carried $200 million worth of silver ingots
• Seabed Worker charter cost $100,000/day
• Recovered 110 tons of silver over 2 years
• Heaviest, deepest salvage effort accomplished at time

San Jose Treasure Ship (Colombia)

• Spanish ship sunk by British warships off Colombia
• Estimated $20 billion worth of gold, silver, precious stones
• Colombia working since 2015 on salvage plans
• Spain and Central American countries made competing claims
• Trend toward government-private company collaboration

Academic Opposition to Commercial Treasure Hunting

• UNESCO and heritage institutions oppose commercial salvage
• Argue shipwrecks provide more value left undisturbed
• Research value vs financial gain debate
• Ships serve as maritime graveyards deserving respect
• Technology could enable profitable removal funding future research

Paleontology Ethics Debate

• Commercial crews vs academic researchers
• Commercial argument: fossils exposed at surface degrade quickly without excavation
• Sales motivate more people to search, leading to more fossils saved
• Academic counter-argument: commercialization leads to loss to science
• Landowners incentivized to work with commercial crews over researchers
• No guarantee fossils sold at auction available for research
• Most major sales go to museums, but risk of private collectors

Industry Renaissance and Future Stakes

• New technology and record-breaking sales driving renaissance
• Treasure hunting artifacts more relevant than ever
• Higher stakes and values increase ownership drama
• Connection between paleontology and statistics in data analysis
