HADROSAURS: HAD- row- sores
Among the last and most numerous dinosaurs to roam the earth,
hadrosaurs (commonly known as duck-billed dinosaurs) were large, oddly
shaped, low-slung plant eaters with tough beaks on their snouts for
shredding vegetation.
Given their extensive fossil remains, it's likely that more
hadrosaurs existed during the latter stages of the Cretaceous period
than any other type of dinosaur .
These gentle creatures roamed the woodlands and plains of North
America, Europe and Asia, some genera in herds of hundreds or thousands
of individuals, and some signaling to each other by funneling blasts of
air through the large, ornate crests on their heads, a characteristic
hadrosaur feature.
Hadrosaurs (Greek for "bulky lizards") were far from the sleekest, or
most attractive, dinosaurs ever to roam the earth. These plant-eaters
were characterized by their thick, squat torsos, massive, inflexible
tails, and tough beaks and numerous cheek teeth (up to 1,000 in some
species) designed for breaking down tough vegetation; some of them had crests on top of their heads, while others didn’t. Like cows and horses, hadrosaurs grazed on all
fours, but some may have been capable of running clumsily away on two
feet to escape predators.
