Martian Iguana

Nasa Raw Image - SOL153 - Iguana, Lizard, Reptile on Mars

What appears to be an Iguana like lizard crawling on the Martian surface. It is "posing" in a fashion nearly identical to that of Earth Iguanas. However, it does not appear to be organic in nature, its surface / skin area is sandy and coarse. It may be a fossilized lizard - or if it is a living organism, it could conceivably have a highly specialized camouflage technique which is very feasible.
