9mm high quality nektaspid arthropod on 67mm slab
Naraoia is a genus of soft-bodied arthropods (Order Nektaspida) that had been classified as a trilobite by some; something like a crustacean by others.  This specimen is one of the earliest-known of a group that survived at least into the Late Silurian.

Study specimen with nice contrast.
