Marginocephalians (meaning "fringed heads") are a group of Ornithischian (bird-hipped) dinosaurs that have a distinctive skull structure (a slight shelf or bony frill on the back of the skull), a unique palate (part of the mouth) and a short pubis (part of the hip).

Description[change | change source]

These herbivores include the ceratopsians (horned dinosaurs like Triceratops, Styracosaurus, Pentaceratops, and Protoceratops) and the pachycephalosaurians (thick-skulled dinosaurs like Stegoceras and Pachycephalosaurus).
