what are carrassial teeth?

Answer 1

its carnassial & not carrassial..anywayz here's the meaning:
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 ower or second upper and third lower molars.
Carnassials are the defining characteristic of the Carnivora order; that is, they are the one thing that all of the animals within the order have in common.
Carnassial teeth all have three roots.
Mountainously large and pointy, the carnassial teeth are designed to shear tough, maybe frozen meats and crush bones. Devastation of the carnassial teeth in a wild carnivore (eg. wolves, lions) may result in the death of the individual due to starvation or incompetence.
