CRANIAL GROWTH AND VARIATION IN EDMONTOSAURS (DINOSAURIA: HADROSAURIDAE): IMPLICATIONS FOR LATEST CRETACEOUS MEGAHERBIVORE DIVERSITY IN NORTH AMERICA.

Cranial growth and variation in edmontosaurs (Dinosauria: Hadrosauridae): implications for latest Cretaceous megaherbivore diversity in North America.

The well-sampled Late Cretaceous fossil record of North America remains the only high-resolution dataset for evaluating patterns of dinosaur diversity leading up to the terminal Cretaceous extinction event.Hadrosaurine hadrosaurids (Dinosauria: Ornithopoda) closely related to Edmontosaurus are among the most common megaherbivores in latest Campania
