Cryptolithus tessellates Trilobites

Here are some pictures of the lace collar sections of the Cryptolithus tessellates trilobite fossils. They were on display at the Cincinnati Museum of Natural History and Science in Ohio, USA (as of August 2013). The trilobites existed in the Ordovician Period and are found in the Edenian Stage of the Cincinnatian Series.
