FOSSILS SPECIMEN: MARGINOCEPHALIA DINOSAURS

Fossils are defined as any evidence of prehistoric life. There are two types of fossils: Body Fossils include remains of skeletal bones, shell, carapace, test and teeth. Trace Fossils are clues the organism existed such as foot prints, tracks, burrows and coprolites (fossil dung).

Marginocephalia meaning “margin-head” are ornithischian dinosaurs that are characterized by a bony shelf or “margin” at the back of the skull. This group includes Pachycephalosaurs and Ceratopsians.To see my model and toy Marginocephalia click here.
