Mars Skull Of Alien T-Rex 'Found' In Photo Of Martian Surface, Except Obviously Not

Conspiracy theorists have identified what they claim to be a 'skull' on the surface of Mars.

The oddly shaped object - which is overwhelmingly likely to be a funny-shaped rock - was discovered in a picture taken by the $2 billion Curiosity rover, and posted to the web by Nasa.

The picture does indeed look like a dinosaur's skull, with spaces for eyes and a jaw-like shape on the bottom half of the rock:

"Something that is real evidence that this could be an ancient skull is the ridge behind the eye socket," posits UFO Sightings Daily, our favourite repository of just-about readable alien fervour.

"Compare both skulls and you will see a lot in common. The eye socket, nasal cavity, behind and above eye bone ridge. Cool find."

The image in question is still on Nasa's website. Nasa hasn't issued a comment yet, because this is a rock.
