- Fossil records indicate that marginocephalians experienced an explosion of diversity and abundance, giving rise to remarkable forms such as Triceratops and Pachycephalosaurus.
- Marginocephalia clade is distinct due to a unique feature – namely an enlarged posterior pelvis in most pachycephalosaurs and ceratopsians.
