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