This is most probably the finest example of this rarely seen species ever found. From the Chisholm Shale of Nevada, this species is noted for its large cephalon and wrap-around genal spines. This Amecephalus piochensis measures 3.6cm (1.4"), and is complete with a small button-like pygidium. The wrinkly details on the cephalon are phenomenal.
