Animal Companions:How to identify [Secondary natural attack]?

[Yagyu Muneyoshi]

ie.

If I choose a Dinosaur(Deinonychus)being my Animal Companions.

On CRB page.54 ,there is no description about its claw are [Secondary natural attack]

But in B1,page.84 have its statistics that Deinonychus's foreclaws are SNA

On the same page in CRB, Horse's hooves are SNA, have"*"and "explanation".

So my question is: Does Deinonychus's (Animal Companions) claw are SNA?
or just have special explanation be considered?
and how about "Digmaul" its tail ?

(Digmaul is a Animal Companions in B5,page.312)

thanks.

Look up the Natural Attacks by Size table under Universal Monster Rules.

The Deinonychus is a special case, it's rear Claws (Talons) are its Primary not is upper Claws (Forclaw), which are secondary.
The Digmaul's Tail is a secondary attack.
You can tell by the -5 difference of the attacks.

Deinonychus wrote:

Melee 2 talons +5 (1d8+2),bite +5 (1d6+2), foreclaws +0 (1d4+1)

Digmaul wrote:

Melee bite +8 (1d6+4), 2 claws +8 (1d4+4), tail +3 (1d4+2)

THIS CHART lists which attack types are primary and secondary.

Oddly, it was recently pointed out to me that the Deinonychus animal companion doesn't have "foreclaws". It has "claws".

It creates the odd situation where a companion gets all primary attacks, but its wildshaped master has to resort to some being secondary.
