This was a "tool" 

I'm so tired of archaeologists interpreting anything they don't understand as simply "art." At the very least call it prehistoric crafts, because they were actually utilized in some way. In the case of this figure, it is a prehistoric fertility "dildo." The male deer is coming up behind the female to mount her.

It would be used on the female before copulation because of the increased fertility perceived to coincide with female orgasm. Note the ridging.

Archaeologists historically are afraid to openly discuss the sexual nature of prehistoric crafts. This is why so many things are labeled "fertility object" when they are dildos, plain and simple. Yes, population increases were the larger goal of this. But the female orgasm was proof that some supernatural force had blessed her womb. 97.64.176.4
