DalmanitinaDescription: This is a fine example of an Ordovician dalmanitid trilobite known as Dalmanitina proeva. It is a colorful example with incredible details. Note the presence of eye facets, something often not preserved, particularly in the right eye. The interesting bicolor matrix is entirely natural and may have been the result of post-depositional seepage of iron-bearing water via a crack in the entombing matrix. I have included a photo of the underside so you can see that it is not the result of compositing.
