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 .

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 ...
For the size comparison, the ornithomimid is too large, length is measured across the vertebral column. Currently the chart doesn't account for the curve in the neck. --Slate Weasel (talk | contribs) 15:06, 26 March 2019 (UTC) I'm not too familiar with this dino but I agree with others here that the calf muscles need work.
Size is an important aspect of dinosaur paleontology, of interest to both the general public and professional scientists. Dinosaurs show some of the most extreme variations in size of any land animal group, ranging from tiny hummingbirds , which can weigh as little as two grams, to the extinct titanosaurs , such as Argentinosaurus and ...
Ceratopsidae (sometimes spelled Ceratopidae) is a family of ceratopsian dinosaurs including Triceratops, Centrosaurus, and Styracosaurus.All known species were quadrupedal herbivores from the Upper Cretaceous.
Skulls of the three species compared: P. perotorum (with inaccurate epiparietal placement), P. canadensis, and P. lakustai Pachyrhinosaurus canadensis, was described in 1950 by Charles Mortram Sternberg based on the holotype incomplete skull NMC 8867, and the paratype incomplete skull NMC 8866, which included the anterior part of the skull but was lacking the right lower mandible, and the "beak".
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.
