NASA’s Mars Curiosity rover has discovered a very interesting sedimentary rock formation in the “Yellowknife Bay” region of Gale Crate that contains blister-like bubbles that look very much like barnacles. We have no idea what these rocks are or what these embedded bumps are, but if this was found on Earth in sedimentary rock, it would most likely be described as some type of fossil. See for yourself. Look at the rocks just above the steel frame of the Curiosity rover on the right of the image. Very interesting find! Can’t wait for the next briefing from the rover’s science team! Could these be fossilized bubbles in the mud? Or are these the first actual fossils discovered on Mars?
