talonid

from The Century Dictionary.

• noun The shelf-like heel developed at the posterior part of the crown of the lower molar teeth of mammals. An analogous structure occurs in the premolars. The talonid is least modified and may be most readily recognized in the lower molar of carnivorous and insectivorous mammals. The homologous structure in the upper teeth is called the talon.
