COVER Depiction of four dinosaurs and dinosaur precursors from fossils found at the Hayden Quarry of northern New Mexico. The dinosaur precursors Dromomeron romeri (lower left) and a Silesaurus-like animal (bottom center) coexisted during the Late Triassic with the dinosaurs Chindesaurus bryansmalli (top center, with crocodylomorph in its mouth) and a coelophysoid theropod (upper right), indicating that the initial rise of dinosaurs was prolonged rather than sudden.
