Naraoia

 Naraoia is a genus of trilobites (or trilobite-like arthropods) found in Cambrian strata of the Burgess Shale and the Maotianshan shales Lagerstätte. They were flattened, oval-shaped animals, with an uncalcified shield that was divided into two regions, a smaller region covering the head, and a larger section covering the body. There are no hint of lobes, as in true trilobites. All species were blind, showing no trace of eyes.

 Naraoia fossils range between 2 and 4 centimetres in length. 392 specimens of Naraoia are known from the Greater Phyllopod bed, where they comprise 0.74% of the community.
