       Paradoxically Micropachycephalosaurus is one of the smallest dinosaurs that we know about,‭ ‬yet it easily has one of the longest names.‭ ‬Micropachycephalosaurus was named from a partially preserved individual that in‭ ‬1978‭ ‬was perceived as what we now call a pachycephalosaur.‭ ‬However more modern analysis in the early portion of the twenty-first century noted that there is no evidence that Micropachycephalosaurus had a thickened skull roof,‭ ‬a key feature for a pachycephalosaur.‭ ‬Micropachycephalosaurus is today considered to more likely be a small ceratopsian dinosaur.‭ ‬This is not that far away from the original classification given that the ceratopsian and pachycephalosaurid dinosaurs are thought to have had a common ancestry within the ornithischian‭ (‬bird hipped‭) ‬dinosaurs.
       Micropachycephalosaurus was a very small dinosaur,‭ ‬and one that was probably reliant upon speed and agility to try and evade predators such as dromaeosaurid and troodontid dinosaurs.
