Is This Really A Fossil? And A Native American Axe In One?

Ok, I am a newb at all this. I am interested in finding a real fossil but after reading several posts, I just decided to ask if this is real or not. I found this on eBay (eBay item number: 271846574029 http://www.ebay.com/itm/271846574029) and it claims to be both a fossil and an axe head carved by a Native American. What are your opinions? If this is true, I can only imagine that it will make this extremely rare and valuable and hard to believe its just being sold on eBay.)

Thanks in advance!
