So what if it looks like a turtle?

OK, I may be in some disagreement with my colleagues who are sending pictures of rocks that look like turtles, or rock piles that look like turtles. I figure I should ask: what is the significance of a rock or rock pile looking like a turtle?

We are aware that the turtle is a very important creature with its thirteen shell plates and it place in the mythology as the creator of earth. But let's take a rock, for example, that everyone agrees looks like a turtle. "There is a turtle....it was revered".

What I am curious about it whether my colleagues leave it at that? I want to propose something else: that the rock with a point on it, and the pile shaped like a turtle had a function which is enhanced by the turtle presence, but that is not the primary characteristics of the feature. 

What I mean is, the pointed rock might cast a sharp shadow, or the turtle pile may have the same function as other piles nearby that lack the turtle shape . In both cases I assume that primary function is made stronger and given more power due to it being a turtle. 

But to have a modern observer experience a turtle shape does not seem to say a lot about the past. So I ask my colleagues what they make of it, beyond observing a turtle's shape?
