In 1970, Hendrickson had a large circle of friends in the diving business, and one day was invited to participate in a
salvage diving expedition off the Florida Keys, which she eagerly undertook. Her job was to retrieve valuable building materials that were stored in a cargo freighter which ran aground on a
coral reef. While continuing her work in salvage, Hendrickson soon found herself exploring old shipwrecks, later going to the
Dominican Republic. She was fascinated by working in the company of archaeologists and fell in love with the country, visiting the island often. By the mid-1980s, Hendrickson had also attempted mining
amber in the Dominican mountains. She had become one of the largest amber providers for scientists. Hendrickson also found three perfect 23-million-year-old butterflies, which make up a half of the whole world's total collection. Although she found the work too monotonous to pursue full-time, writing that "You could dig for months and find nothing in the Dominican caves," she continued studying
paleo entomology, becoming an expert at identifying fossilized insects. discovered by Sue Hendrickson She also met Swiss paleontologist Kirby Siber, who allowed her to join his team consisting of paleontologists Carlos Martin and
Peter Larson. The group began excavating
Miocene baleen whale fossils at an ancient seabed in Peru, and Hendrickson joined the team for several summers, discovering fossilized dolphins, whales, and sharks. On August 12, 1990, while examining a cliff-side in South Dakota with a team from the Black Hills Institute, she discovered a
Tyrannosaurus rex specimen – the largest, most complete, and best preserved
T. rex ever found. The specimen was later named "
Sue" in her honor. In 1992, Hendrickson joined a team of marine
archaeologists headed by
Franck Goddio. With them, she took part in many diving expeditions, the most notable of which were the Royal Quarters of
Cleopatra, and
Napoleon Bonaparte's lost fleet from the
Battle of the Nile. In 2005,
Glamour magazine honored her in their "Glamour Woman of the Year Awards". In 2001, she published an autobiography entitled
Hunt for the Past: My Life as an Explorer (New York, NY: Scholastic, Inc). In 2008, she was featured on the "Dare to Explore" chapter of
National Geographic Kids. Hendrickson now lives on the island of
Guanaja, off the coast of
Honduras. She is a member of the
Paleontological Society,
Explorers Club,
Society for Historical Archaeology, and was awarded an
honorary Ph.D. from the
University of Illinois at Chicago in 2000. ==References==
