Does this mean that at level 6 I can Wild Shape into Huge dinosaurs (usually not available until level 8)
Yep.
Someone in my current group (that I warned repeatedly against the idea) is a Wolf Shaman. He did this because he loves the flavor, and also because he didn't understand that he wouldn't be getting iterative attacks with his Bite and that you can't take on a template so he can't just be progressively bigger wolves.
He is upset, but his secondary plan is relying on the elemental forms druids get later, claiming that the Wolf druid is treated as two levels higher when taking on the form of a canine, and that elementals can certainly take on the form of a canine creature as most of them have descriptions like:
"Most earth elementals look like terrestrial animals made out of rock, earth, or even crystal, with glowing gemstones for eyes."
I wish he'd just listen to me and get rid of the archetype before the game goes on too long and the GM suspends any rebuilding amnesty, but I can't find anything to disprove his claim exactly--I mean, it might not even necessarily be against the spirit of the rule, because without getting elementals in there, the rule is pretty limiting and sucky, and a big fiery wolf is kind of badass.

Another option is to use Jason's suggestions on house-ruling templates that can be applied to the totem animal. He talks about it in that thread. Here, here, here, and at the end of this post here.

Thanks for the info, Grick.
