Hadrosaurids
These “big (bulky) lizards” get the nickname “duckbills” from their broad, toothless beaks; yet, farther back, their jaws were crammed with batteries of grinding teeth - more teeth than any other dinosaurs possessed. Evolving possibly in Late Cretaceous Asia, these harmless browsing bipeds reached Europe and South America, and became among the most abundant dinosaurs of North America.
