The object certainly resembles a fossilized femur, but the odds that it’s anything other than a weird-looking rock are, well, astronomical.
But NASA hasn’t been too impressed.
“On Mars, as on Earth, sometimes things can take on an unusual appearance,” NASA wrote on its website last year after a strange, “shiny” object was spotted on the Martian surface.
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.”
The Huffington Post reached out to NASA for comment about the “bone.” This post will be updated with any new developments.
