Strange ship-like object spotted by Mars rover Curiosity

Despite NASA’s proven manipulation of Mars photographs researchers continue finding unusual anomalies in the photographs.

Yet again a strange large anomaly is spotted in a photograph captured by Mars rover Curiosity. 

As the object does not seem very natural and does not fit into the surrounding landscape we may wonder what it is and how it ended up there.
