Travel through 165 million years of American dinosaur history — one formation, fossil, and species at a time.

Dinosaurs of the United States is a richly illustrated field encyclopaedia featuring 48 dinosaurs discovered across the American West and Great Plains. Meet the early hunters of the Triassic Southwest, the immense sauropods and plated herbivores of the Jurassic Morrison Formation, the feathered predators of the Early Cretaceous, and the last great communities of Tyrannosaurus, Triceratops, Edmontosaurus, and Ankylosaurus.

Every two-page profile combines original palaeoart with quick-reference facts, anatomy, habitat, fossil history, and an evidence-focused field note. Regional guides, a formation directory, glossary, selected references, and responsible fossil-discovery advice place each animal in its correct time and landscape.

Created for curious adults, families, older students, museum visitors, and lifelong dinosaur enthusiasts, this is a visual journey through the rocks that made American palaeontology famous.
