Book excerpt: When Peter Larson and his team from the Black Hills Institute discovered the world's largest and most complete Tyrannosaurus rex skeleton beneath a South Dakota butte in 1990, they had no idea that it would be the find of a lifetime. Sue, as the skeleton came to be known, would ultimately not only lead them to international recognition, but also pull them into a world of FBI investigations, Native American land claims, competitive paleontologists, and avaricious museum curators. This gripping story chronicles the adventures of Larson and his group, explaining the art, technology, and politics behind one of the most successful group of T-rex hunters.
