The '''hypocone''' is the name for a main [[cusp (dentistry)|cusp]] found on the [[Molar (tooth)|molars]] of the upper [[dentition]] of [[hominids]] and other [[theria]]n Mammals.  It is found on the distal lingual side of the tooth. It fits into the grooves of the lower dentition and is an [[adaptation]] for the overall grinding and tearing of foods using the occlusal (chewing side) of the tooth surface during [[Occlusion (dentistry)|occlusion]] or [[mastication]] (chewing).  Its strength is due to the thickness of the [[Tooth enamel|enamel]] which differs among species of hominids. The hypocone appears to have evolved independently in more than twenty mammal species during the Cenozoic period.<ref name="The hypocone as a key innovation in mammalian evolution">{{cite journal | pmc = 40683 | pmid=7479871 | volume=92 | title=The hypocone as a key innovation in mammalian evolution | year=1995 | journal=Proc.
