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 .
Size estimates for the largest Pachyrhinosaurus species, P. canadensis indicate lengths of 6–8 metres (19.7–26.2 ft) and a weight of 3–4 tonnes (3.3–4.4 tons). [ 10 ] [ 11 ] [ 12 ] The other species, P. lakustai and P. perotorum , have been estimated by Greg Paul at 5 metres (16.4 ft) in length and 2 tonnes (2.2 tons) in weight. [ 11 ]
The small size of most pachycephalosaur species and lack of skeletal adaptation indicates that they were not climbers and primarily ate food close to the ground. Mallon et al. (2013) examined herbivore coexistence on the island continent of Laramidia , during the Late Cretaceous and concluded that pachycephalosaurids were generally restricted ...
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.
Ralph Chapman and others performed a detailed statistical analysis on the relative size of dome to braincase in 23 Stegoceras validum domes and domes from 6 other pachycephalosaur taxa. They were able to account for the age and development of the specimens using the size of the braincase as an indicator.

English: Size comparison of the holotype specimen (HIIUC-BN00) of Thyreosaurus atlasicus with an adult human male (~1.8 m) for reference. Note: While Thyreosaurus can be reconstructed as a dacentrurine stegosaur with reasonable confidence, the structure and arrangement of its unusual osteoderms are much less certain. Traditional stegosaur ...
