=== Skull ===
''Moropus''<nowiki/>' skull was fairly small compared to its body.<ref name=":7">{{Cite journal |last=Coombs |first=Margery Chalifoux |date=1983 |title=Large Mammalian Clawed Herbivores: A Comparative Study |url=https://www.jstor.org/stable/3137420 |journal=Transactions of the American Philosophical Society |volume=73 |issue=7 |pages=1–96 |doi=10.2307/3137420|jstor=3137420 |url-access=subscription }}</ref> It was narrow, and bore high [[Nasal bone|nasal bones]]. The snout had a spoon-shaped tip, a characteristic common to selective [[Browsing (herbivory)|browsers]]. It suggests the presence of mobile lips and possibly a long tongue.<ref name=":7" /> [[William Berryman Scott]] suggested that the tongue may have been used in conjunction with the upper lip to pull down branches.<ref>{{Cite book |last=Scott |first=William Berryman |author-link=William Berryman Scott |url=https://www.biodiversitylibrary.org/bibliography/54974 |title=A history of land mammals in the Western Hemisphere; illustrated with 32 plates and more than 100 drawings |date=1913 |publisher=Macmillan |location=New York}}</ref> The lower [[Incisor|incisors]] protruded forwards, and the [[premaxilla]] is [[Toothlessness|toothless]], similar to in modern [[Ruminant|ruminants]]. This would have formed a cropping mechanism for processing vegetation. There was a [[diastema]] (gap) separating the incisors from the [[cheek teeth]], which would have allowed the tongue to extrude from the mouth.<ref name=":7" /> The [[maxilla]] was similar to that of modern horses (''[[Equus (genus)|Equus]]'').<ref name=":0" /> Some specimens (or species) ''Moropus'' did not have a [[sagittal crest]],<ref name=":2" /> while others did, even as juveniles.<ref name=":0" />
