NASA’s Curiosity rover has spotted a "thigh bone" on Mars -- or at least that’s what some paranormal types would have you believe.

The folks at UFO Blogger wrote this week that the rover’s MastCam had captured a photograph of a "fossilized thigh bone" on the red planet on August 14.

The object certainly resembles a fossilized femur, but the odds that it's anything other than a weird-looking rock are, well, astronomical.

Over the years, people eyeing pictures from Mars have claimed to have seen everything from an iguana to a finger to weird faces.

But NASA hasn't been too impressed.

NASA said at the time that while the "shiny-looking rock" resembled a car door handle or another metallic object, its actual identity was probably a bit more prosaic. As Ron Sletten, a scientist on the Curiosity team, indicated on the agency's site, "the object is an interesting study in how wind and the natural elements cause erosion and other effects on various types of rocks."
