David K. Randall, author of The Monster's Bones: The Discovery of T. Rex and How It Shook Our World, recounts the historic discovery of the Tyrannosaurus rex by pioneering paleontologist Barnum Brown. The narrative traces Brown's journey from a Kansas farm to his recruitment by Henry Fairfield Osborn for the American Museum of Natural History. Driven by Gilded Age competition funded by wealthy industrialists, Brown used geological expertise and dynamite in 1902 to unearth the first T. rex fossils in Hell Creek, Montana. Despite facing devastating personal tragedy, Brown's efforts culminated in the legendary 1915 public mounting of the apex predator in New York, forever transforming the public's understanding of prehistoric life.
