In case anyone's still curious, it seems that these flat little ramshorns belong to the genus Gyraulus, which has many species, a worldwide distribution, and a long fossil history, at least according to what I gathered from a Google search.  Here is a source with an image and a little info: http://animaldiversity.ummz.umich.edu/s ... /view.html
