That looks a lot like the impression left from a Philips screw head that has been pressed into the soil, since the image is from the Microscopic Imager it would be helpful to know the scale of the impression, if the artifact is in the 2 to 8 mm range, I would guess that part of the instrumentation used to position the Microscopic Imager was moved into contact with the surface leaving the mark of the screw.
