Hip bones of an ornithischian
|
These bird-hipped dinosaurs had pelvises
that resembled those of birds. Ornithischian dinosaurs
were all plant-eaters and included the stegosaurs,
ankylosaurs, hadrosaurs, ceratopsids and pachycephalosaurs.
Each had a toothless 'beak' at the front of the
lower jaw that was used for gathering, plucking
or cropping vegetation. Although their name implies
a relationship, the ornithischians did not give
rise to birds. |
