Carnassial Teeth
Definition
The large, blade-like shearing teeth (upper fourth premolar and lower first molar in dogs and cats) that carnivores use to slice through muscle and tendon. Their marks are characteristically linear cuts or score marks on bone, which distinguish carnivore feeding from human bite marks.

Common questions
What features separate carnassial shearing marks from a human bite?+
Carnassial marks are narrow, linear scores or cuts concentrated at shaft edges from a shearing action, while human bites leave paired arcs of individual tooth pressure and puncture marks reflecting the rounded human dental arcade.
Why does identifying carnassial damage matter in a death investigation?+
Misreading carnivore scavenging as perimortem sharp-force trauma, or vice versa, can change the interpretation of cause and manner of death, so examiners check mark morphology and location against known scavenger feeding patterns before drawing conclusions.
