Looking for the small or medium animal with most single attack damage

[ShoulderPatch]

Creature must come from Bestiary 1-4
Size must be Small or Medium
Type must be Animal
Can't be aquatic, could be flying
No other stat matters, just what is the highest single attack (ideally a creature with only 1 attack form for 1.5x str bonus to dmg)

So far "Giant Porcupine" from Bestiary 3 with it's 2d6 tail slap seems to be the highest, anything with 3d4, 3d6, etc that I might have missed, or other 2d6 contenders?

Giant Porcupine is it. For small I have the vulture at a 1d6 bite.

The only bigger attack is the bull shark at 2d8, but as you noticed, it is aquatic.

Tasmanian Devil, of course. Bugs'll tell you. :)
