Aydin Orstan wrote, I suppose such fossils have no real value for their exact source cannot reliably be located. Usually, this is so. In exceptional cases, the fossiliferous rock can be traced to a unique quarry. For instance, on Interstate Highway 20/59 at the Coaling exit a few miles (kilometers) east of Tuscaloosa, Alabama, the Middle Ordovician riprap derives from a local quarry near Woodstock. There are very few quarries in this formation (the Chickamauga Limestone) in this state, and no others are nearby. The quarry and riprap yield identical rocks and fossils (brachiopods, bryozoans, occasional trilobites, crinoids, etc.) and both have equivalent value. Even so, I label the quarry and riprap collections separately, on the principle, "Never do anything to a shell that you can't reverse." Andrew K.
