I mentioned my own shop back on page one here, but wanted to drop in again to mention
http://www.etsy.com/shop/HereInSmallTownUSA She has bones, dried animal bits, and even animals (and bits of them) in jars, all ethically acquired and at remarkably reasonable prices. Not for the feint of heart, but great curio cabinet items among other things. I've purchased several items from her and I've never been disappointed.
While I'm at it, I just made a coupon code for you guys-- enter "brassgoggles" with your order for a 10% discount in my shop!
http://katarinanavane.etsy.comI've also listed quite a few new items lately.
