Weird Rock on Mars

Im on the phone now, maybe thats why it isnt a live link?
 
One day a rover is going to dig up a silver dime.

Then all the other rovers will start digging in the same place.
 
First thing I thought of was how pretty it is. I would make a nice jewelry set out of it. NASA needs to send this home lol. My second thought was could this be a skeleton of some creature?
