hi, deerhunter, the ripple mark specialist on this forum, are rather to be found at the uk section of this forum, unfortunately.
I have never seen ripple marks like yours, and the wave pattern in between the ripples, might be trace fossils! it's always interesting, if somebody used "fossil containing stone" as building material. if you get no answer (I would like to know too) maybe I would pay of do, send a privat message to some of the dino specialists here, to have a look at your post.
