 Present in most herbivores, these patterns of lophs can be a simple, ring-like edge, as in mole rats, or a complex arrangement of series of ridges and cross-ridges, as those in odd-toed ungulates, such as equids.Lophodont molars have hard and elongated enamel ridges called lophs oriented either along or perpendicular to the dental row.Lophodont molars are common in herbivores that grind their food thoroughly.
