Skull found on Mars!

The Mars Rovers have found a human skull on the red planet! Or so DJ said last night. I couldn't find any mention of it in the news, but I did find it on some zany web site dedicated to "Mars anomaly research".

Before we start filming episodes of CSI: Mars, we should probably ask ourselves some questions. What do we make of this subtle play of light and shadow? Shall we believe that Mars is strewn with human remains? Or reject it as another cockamamy product of the human imagination?
