Lophodont
When two lophs form transverse, often ring-shaped, ridges on a tooth, the arrangement is called bilophodont. This pattern is common in primates, but can also be found in lagomorphs (hares, rabbits, and pikas) and some rodents. Further development of lophodonty can extend to three transverse lophs (trilophodonty), or transverse lophs linking a series of cusps (zygodonty)
