At 23:13:14 UTC the Mars Hand Lens Imager (MAHLI) took this photo of a Martian rock from a distance of 12.9 cm and with a definition of 0.0532 mm/pixel, thus covering an area of 8.36 cm X 6.24 cm.
A snail-shaped structure creeps between the layers of this sedimentary rock; to make it easier to see, I have enlarged the detail of interest three times the original size and placed the magnification immediately below the detail itself.
A shape of this type can certainly not be attributable to geological phenomena and is therefore of extreme interest. The detail is almost at the limit of the resolution of the photo, however it is clearly identifiable, especially if you look at the image in 1:1 scale.
I really hope that the detail does not go unnoticed as it could be the first example of a fossil photographed on the Martian surface!
This photo has been processed to allow for better color vision by balancing the white and slightly increasing the microcontrast and color saturation.
