NASA has published photographs of star-shaped and swallowtail rock formations discovered by the Mars Rover Curiosity during the exploration of the area of Gale Crater on Mars called Vera Rubin Ridge. This ridge is offering interesting research cues, in this case gypsum crystals similar to those found in lakes that dried up on Earth, for example in Scotland. This is another clue of the fact that in Gale Crater in ancient times there was a lake.
