(Image credit: NASA/JPL-Caltech/MSSS/Kevin M. Gill) A section of Mars is covered in a surprising number of features that look like clumps of giant, fossilized reptile scales, new photos reveal. But don't be alarmed ‪—‬ the strange structures did not originate from monstrous aliens. Instead, they may have ties to ancient water. NASA 's Curiosity rover snapped the photos of the peculiar rocks as it was driving toward Antofagasta — a relatively young, 33-foot-wide (10 meters) impact crater located on the slopes of Mount Sharp (also called Aeolis Mons), which stands in the larger Gale crater, near Mars' equator. A pair of black-and-white photos of the "scales" was released by NASA April 14, while a close-up color image of the rocks was shared online the next day by Kevin M.…
