I'm glad you bumped this post, as I'm interested to see what comes out of it as well.

As much as I like Tribe, I find the archaeology tribes here have very little activity. You might consider asking in one of the more specialized forums, like the one at www.archaeologyfieldwork.com/for....php

My own interest in archaeology is also somewhat specific, mostly focused on Mojave rock art with keen attention on the northwestern region simply because that's where I do a lot of hiking so I have opportunity to visit many of the sites I read about and sometimes even find a few of my own.

I began my search for info on the region with a good many long nights with Google, which turned up a lot of irrelevant material but also helped me find gems like this:
petroglyphs.us/article_co...ep_cult.htm
(It's not at all related to your area of interest, but you might find it a good read just the same if only for the open-mindedness of the author as he discusses various interpretations of the slender available evidence of the Coso culture.)

As my readings expanded eventually I found myself with questions that I couldn't find the answers to in public materials, and needed just the sort of guidance it sounds like you're looking for with your interest in Aurignacian culture. Being a dilettante in this field, I tried my best to find the answers on my own, but when I came up short I risked writing the author of the article I cited above, Dr. Garfinkel. That turned out to be the luckiest break I've had: he generously offered several good pointers to very specific information, and we've maintained a correspondence which has enriched me greatly on many levels.

It's not often the case that life affords us the opportunity to find mentors, but it seems it doesn't hurt to try. Perhaps you'll be as fortunate in finding such a resource for your interests, and along the way you'll certainly find the book recommendations you're looking for.

Best of luck in your journey. And if you find a good book, please post what you find here. Thanks.
