No need to worry, folks. It’s certainly not the bone of an alien or a hyper-ape, and there’s nothing anachronistic about it. Just a rock. Yup, no biggie.
NASA released Curiosity’s “thigh bone” Mars rock photo with an explanation on Thursday.In the photo description, NASA officials wrote that while “this Mars rock may look like a femur thigh bone,” it is not the fossilized remains of a mysterious Martian. “Mission science team members think its shape is likely sculpted by erosion, either wind or water.”The Curiosity rover has found evidence that Mars was once a habitable place in the ancient past, but there is no evidence that creatures large enough to leave a bone behind ever existed on the planet.
