Are horse teeth lophodont?
occurrence in horses, tapirs, and rhinoceroses …of this kind are called lophodont. Lower molars typically have two transverse lophs, the protoloph and the metaloph. In the upper molars these ridges are fused with a longitudinal ridge (ectoloph), which runs along the outer edge of the tooth.
What is lophodont dentition?
