       | in many places along the Fundy shore in Nova Scotia, and I have
       | hauled slabs back up the hill, and some made it into the house:)
       | And in very closely related or the same ?, rocks are fossils,lots
       | and lots of fossils, of which I also have hauled back chunks and
       | slabs.,.. I never bothered to study the exact relationship
       | between stratification layers ......but I will now ! edit: the
       | wave ripples I find are sometimes very clear, and what makes it
       | more interesting is that litteraly within several hundred feet,
       | are exactly the same ripples in the modern beach, and they are
       | created at the same scale, and larger, and in high current areas
       | with very fine sand, get large, large and dangerous to walk
       | through as there is quick sand in spots....so it will be trapping
       | and burying whatevr gets deposited. The relavance bieng, that the
       | mars rover is likely in an exceptionaly good spot for looking for
       | fosils on any scale.

       | Imagine the frenzy if we even found the tip of some kind of
       | plant/fungus organism growth. It would be potentially the biggest
