On August 12, 1990, in the badlands of South Dakota, paleontologist Peter Larson and his team from the Black Hills Institute unearthed the largest, most complete Tyrannosaurus rex ever found. It was the find of a lifetime. They named the dinosaur Sue. Two years later, when the FBI and the National Guard showed up, battle lines were drawn over the ownership of Sue. The U.S. Government, world-class museums, Native American tribes and competing paleontologists became the Goliath to Larson's David as Larson and his team fought to keep their discovery. Dinosaur 13 chronicles the unprecedented saga and details the fierce battle to possess a 65-million-year-old treasure. Filmmaker Todd Miller excavated layer after layer, exposing human emotion in a dramatic tale that is as complex as it is fascinating. Dinosaur 13 is based on the book, "Rex Appeal," written by Peter Larson and Kristin Donnan-Standard. The film is featured at the Black Hills Film Festival in Hill City Saturday afternoon. Miller and Donnan-Standard joined Karl Gehrke in SDPB's Rapid City studio.
