The above discoveries were made in 2019. Mars curiosity rover has thousands of images and some of them are of good quality. I have found most of these images on Gigapan. Mars reminds me of an ancient coral reef in many places. I try to publish the best ones I can find. Some are very definite and some still leaves questions. Of course there was life on this planet in the past and many of these dead objects have fossilized into definite structures. You be the judge.
