Dilambodont Molars :a functional interpretation of their evolutionPercy M. ButlerKeywords: Convergent evolution; Dilambdodont; Molar function; Molar teethCite this article: Butler P. M., 1996. Dilambodont Molars :a functional interpretation of their evolution. Palaeovertebrata 25 (2-4): 205-213. AbstractIn dilambdodont molars the primitive crest between paracone and metacone (centrocrista) is represented by a pair of crests that join the mesostyle (postparacrista, premetacrista). The cutting action of these crests against the crests of the hypoconid is described. Dilambdodonty is a derived adaptation for greater cutting efficiency. It has evolved several times and in more than one way. Published in Vol. 25, Fasc. 2-4 (1996) |
