Using natural weapons to sunder

[Tav_Behemoth]

Is there any circumstance, short of a magic fang spell, in which a creature with a natural attack can sunder a magical weapon?

An attacker cannot damage a magic weapon that has an enhancement bonus unless his own weapon has at least as high an enhancement bonus as the weapon or shield struck.

I seem to remember something about how creatures with damage resistance count their natural weapons as being able to overcome that same type of damage resistance -- but I can't find it, and this wouldn't resolve whether a creature with DR 5/magic can sunder a +1 or +2 sword in any case.

The DMG Errata removed that sentence from the rules. You can use anything to sunder a magic weapon. (The more pluses the weapon has, the more hardness and hit points it has.)

Thanks! Will have to start using an errata'd SRD.

Two points:
1: The thing about needing at least a +X weapon to sunder another +X weapon has been deleted in errata. Note that they changed the bonus to hardness and hp from enhancement bonus to compensate, +2 hardness and +10 hp per plus (the rule books say +1/+1 in one place, and +2/+10 in another - it's the latter that's correct).
2: Having DR does not, in general, give you the ability to penetrate that type of DR. DR X/magic makes your natural weapons count as magic, and DR X/epic does the same for epic. Other DR doesn't (though having an alignment subtype makes both natural and wielded weapons count as that alignment too, see the description of most outsiders).
