Snail shells on Mars!!

This is the picture that was taken recently by the Mars Curiosity rover.

The (boys) were concerned about the white shiny object, wondering if it was plastic from the rover.

A "big wig" examined the photo and said that it looked like part of the formation.

Here is a section of the photo enlarged and point out what looks to me like snail shell fossils.

Here is the photo with a picture of an earth snail shell super imposed. It even coils in the same clock-wise direction!  To Zoom in press and hold (ctrl) then press (+) 1, 2 or more times.  

SEE IF YOU CAN FIND MORE FOSSILS.
