Wikipedia
Ornithopods or members of the clade Ornithopoda ( or ) are a group of ornithischian dinosaurs that started out as small, bipedal running grazers, and grew in size and numbers until they became one of the most successful groups of herbivores in the Cretaceous world, and dominated the North American landscape. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex in the duck-bills (hadrosaurs), before they were wiped out by the Cretaceous–Paleogene extinction event along with all other non- avian dinosaurs. Members are known from all seven continents, though they are generally rare in the Southern Hemisphere.

The ornithopods, in turn, are close to other contemporary groups, the horned, ceratopsian dinosaurs and the domeheaded pachycephalosaurs.
To the east, the land slopes up to a plateau, good for ceratopsians, while to the south is flat country with more sauropod swamps and lots of ornithopod: duckbill and iguanodont.
The duckbill, like the other ornithopods, are wary beasts because they have neither armor nor weapons.
Indeed, neither Stromer and Markgraf nor the 2000 expedition team ever found evidence of ornithopods, though they have been found in Early Cretaceous sediments in Niger.
