Here is an image of a nice plate of fossils found in the Lexington Limestone of Franklin County, Kentucky USA. There are at least 8 Tentaculites richmonensis shown in the image around that brown object which is an Isotelus trilobites hypostome (feeding scoop). Also in the images are brachiopods and bryozoans. Fossils date to the Ordovician Period.
Thanks to Kenny for image.
