† Augustynolophus morrisi was a Late Cretaceous saurolophine hadrosaur from the Moreno Formation of California, United States. This large herbivore is the official state dinosaur of California and represents a rare record of hadrosaurid diversity from the West Coast. It inhabited coastal floodplains near the end of the Cretaceous approximately 66–68 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
