Micropachycephalosaurus (meaning "small thick-headed lizard") is an extinct genus of basal marginocephalian dinosaur containing only the type species, Micropachycephalosaurus hongtuyanensis. It lived in China during the Late Cretaceous ( Campanian ) and was found in the Jiangjunding Formation .
Skulls can be domed, flat, or wedge-shaped depending on the species, and are all heavily ossified. The domes were often surrounded by nodes and/or spikes. Partial skeletons have been found of several pachycephalosaur species, but to date no complete skeletons have been discovered. Often isolated skull fragments are the only bones that are found ...

Dong Zhiming described the new genus and species Micropachycephalosaurus hongtuyanensis. [7] He also proposed that the flat-headed pachycephalosaurs constituted a distinct family called the Homalocephalidae. [10] Skull of Gravitholus viewed from above. The arrows point out lesions in the bone.
Marginocephalia (/ ˌ m ɑːr dʒ ə n oʊ s ə ˈ f æ l i ə / Latin: margin-head) is a clade of ornithischian dinosaurs that is characterized by a bony shelf or margin at the back of the skull.
Pachycephalosaurus is the largest-known pachycephalosaur, known for having an extremely thick, slightly domed skull roof; visually, the structure of the skull suggests a ‘battering ram' function in life, evolved for use as a defensive mechanism or intra-species combat, similar to what is seen with today's bighorn sheep or muskoxen (with male ...
Much of its skeleton is known, including the entirety of the skull Yingshanosaurus: 1994 Shaximiao Formation (Middle Jurassic, Bathonian) China: Possessed greatly enlarged shoulder spines Yinlong: 2006 Shishugou Formation (Late Jurassic, Oxfordian) China: Its skull displays features of ceratopsians, pachycephalosaurs and heterodontosaurids ...
Archaeoceratops, meaning "ancient horned face", is a genus of basal neoceratopsian dinosaur from the Early Cretaceous (Aptian stage) of north central China.It appears to have been bipedal and quite small, reaching 0.9 m (3.0 ft) in length and 10 kg (22 lb) in body mass. [2]
