I'm interested in bidding for these sand dollars on our favorite website, but the seller can't tell me where they are from or what the statigraphy is. There are quite a few of them available on various websites, but they hardly give any more information about them. Most of them appear to be from Morocco, although I also saw similar ones from Florida. The given stratigraphy ranges from Cretaceous to Pleistocene and no one names even a genus, let alone a species. I sure would appreciate some details about them if anyone here in the forum has some in-depth information about them.
