This creature resembles both a mammal and a reptile. Its long skull sports a massive maw with saberlike canine teeth. Its muscular frame sits atop pillarlike legs, and a thick tail lashes behind it.

An arctognathus attempts to sink its saber-like teeth into prey, drag it to the ground, and tear it to shreds.
Augmented Critical (Ex): The saber teeth of an arctognathus strike with deadly precision. An arctognathus’s bite attack threatens a critical hit on a roll of 19-20 and deals x3 damage on a successful critical hit.
Tear Fallen (Ex): An arctognathus can deal an addition +1d6 points of damage to a prone opponent.
Trip (Ex): An arctognathus that hits with a bite attack can attempt to make a trip check (+4 modifier) as a free action without making a touch attack or provoking an attack of opportunity. If the attack fails, the opponent cannot react to trip the arctognathus.
