Double Coltraneia Plate - Tower Eyed Trilobites

This is a plate with two Coltraneia trilobites with amazing "tower eyes" full of hundreds of eye facets. The species has often been referred to as a Treveropyge in the past. This specimen has been prepared so that they appear to crawl over the matrix. The arched trilobite would be about 2.6" long if fully outstretched and the second one is 2.3" long. Both trilobites have nice eye facet preservation.
