The lines in the rock does remind one of a shell. But there is no reason to assume that a shell would be on the surface of Mars.

There are many physical processes that could create lines and bubbles in a rock like that, such as sedimentation, trapped carbon dioxide gas or different chemical mixtures solidifying at different temperatures in cooling magma. If you look at the rock in the bottom right corner of the top photo, you can see similar structures, yet that is clearly not a shell. But it is very difficult to determine what caused those structures from just a photo. That is why so many scientists are hoping for a sample-and-return mission to Mars: to clear up questions like these.
