Sandseals on Mars?

[Goggs Mackay]

I was looking at an image of Mars from Curiosity Rover. I noticed what looks like an hexagonal shaped depression in the ground with what looks like a seal (not a real one of course) coming out of the left of the hexagon. So I've drawn on an image to highlight what I could see and I've also inserted an untouched image so you can decide how much was due to my own mind filling in the blanks!




And the untouched image:

Nope, sand seagull, they love the sand anyway. Or, a pigeon with a penchant for the sandbox.

Ha Ha it really does look like a petrified seal!

If you have not seen it I recommend watching "cave of forgotten dreams" as lots of the cave paintings highlight the natural contours of the rock, giving the "paintings" an almost organic feel.
I was amazed at the skill of the artists. below is one example.

the paintings can be roughly dated to about 40,000 yes forty thousand years ago!

Yeah..a rock..an intresting rock...but a rock...

What I was trying to say is that people are predisposed to see faces and forms in objects or surfaces, I am no expert in this, but I understand it is to do with how our vision works.
