In carnivores, the carnassial teeth are the last upper premolar combined with the first lower molar teeth. The carnassials are used for shearing meat.

Carnassials are large teeth found in carnivorous mammals, designed for shearing flesh and bone in a scissor-like way. In the Carnivora, the carnassials are the modified last upper premolar and the first lower molar, but in the prehistoric creodonts, the carnassials were further back in the jaw - first upper and second lower or second upper and third lower molars.
