The authors of this title are curators of the spectacular reinstallation of the Hall of Dinosaurs at the American Museum of Natural History. Documenting the museum's unparalleled collection of dinosaur skeletons, drawing on its vast archive of photographs, maps, books, charts, and recounting the experiences of paleontologists who have scoured remote lands in search of evidence of these ultimately doomed animals, the authors illuminate what the fossil bones, skin impressions, eggs, and footprints reveal to contemporary scientists about the nature of dinosaurs.
