From the dust of the Gilded Age Bone Wars, two vastly different men emerge to fill the empty halls of New York’s struggling American Museum of Natural History: socialite Henry Fairfield Osborn and intrepid fossil hunter Barnum Brown.

When Brown unearths the first Tyrannosaurus Rex fossils, Osborn sees a path to save his museum from irrelevancy. As the public turns out in droves to cower before this bone-chilling giant of the past and wonder at the mysteries of its disappearance, Brown and Osborn turn dinosaurs into a beloved part of culture.

Randall journeys from prehistory to present day, from remote Patagonia to the unforgiving Badlands of the American West to the penthouses of Manhattan.The Monster’s Bonesreveals how a monster of a bygone era ignited a new understanding of our planet and our place within it.
