Sorry, no.
From the Bestiary 1, Natural Attacks:
Primary attacks are made using the creature's full base attack bonus and add the creature's full Strength bonus on damage rolls. Secondary attacks are made using the creature's base attack bonus –5 and add only 1/2 the creature's Strength bonus on damage rolls.
Animal Fury:
While raging, the barbarian gains a bite attack. If used as part of a full attack action, the bite attack is made at the barbarian's full base attack bonus –5. If the bite hits, it deals 1d4 points of damage (assuming the barbarian is Medium; 1d3 points of damage if Small) plus half the barbarian's Strength modifier.
It should've been stated under Animal Fury that it is a secondary attack.

I believe the assumption there is that the full attack mentioned is a normal iterative one, that the bite is being used in addition to... the bite is still primary, but all primary weapons are 'downgraded' to secondary when added to iteratives. if you didn't use the iteratives, the bite would be used as a primary weapon, as it is when NOT full attacking (when you should apply full STR dmg). this is one i've been hoping they fix for a while... maybe next printing. we can FAQ it in the meantime. there's a couple other similar cases, which i can't remember off the top of my head.

Exactly. Animal Fury is an example of an ability with 'reminder text', which describes how the ability works in the most common situation for most players in the ability description, so that they dont have to refer to the bestiary just to use their shiny barbarian ability.
None of that changes that its still a Bite attack, which is a primary natural attack.
This was clarified by some Dev, I just dont remember which one... at some point.
That said, Animal Fury DOES have additional rules for how it applies in a grapple, which is above and beyond a normal bite.

It's those extra rules that cause the issue, nice though they are. If it does different damage and has different rules maybe it isn't a normal primary attack? I assume it is, but with PFS I could have 30 different GMs and need something reliable.
With the 1.5x strength as an only natural attack it makes for an interesting build though, especially if I don't focus on iterative attacks (Cleave etc). Not too hot with Vital Strike though, at d4...

Found the clarification.

Its a bite first and foremost, and the text is there so players dont have to refer to the Bestiary.
