After the Curiosity rover photographed some mudstone in an area nicknamed "Yellowknife Bay", it moved on to new outcrops. A scientist named Nora Noffke studied the photos of the rocks in the "Yellowknife Bay" area, and published a paper in which she interpreted what she saw in the photos. What was her interpretation

The presence of mustones by curiosity rover indicates chances of ancient life.

Explanation:

The Yellowknife bay is a geologic formation of the Gale crater on the planet Mars and NASA named the rover as a curiosity. Its primary goal was to assess the potential habitability and whether the mars are capable to support life.  The presence of the mudstones in the geologic depression area on mars leads to its name as Yellowknife i.e the capital of the northwest territory of Canada. The findings of the mudstone from the stepped bedded stata indicate the clay minerals that show the presence of water and claims that an ancient creator was found on in this region and these indicators of a potential mafic source of origin of deposition.
