I found this footprint on Mars that looks like a human shoe print. The footprint was in a Mars rover photo and might not be a recent print, but may actually be the foot print of a bipedal species that walked this planet long ago. The foot print could be a petrified footprint, much like the dinosaur foot prints found here on Earth.
