Here is a good sample from the ventral body side that shows nicely the legs and the digestive system. Naraoiids are a simple diversified group inside the Arthopoda. Although they have lot of affinity's with trilobites they are handled as an independent, "cognate" group. This results are based on the fact that Naraoiids do not have a calcium- carbonate hardened body parts. It is also improbable that they are a progenetic group. In newer publications there are more handled as Trilobites. So maybe the old fashioned term lather trilobites fits very good for these strange organism .
