|  This
exceptionally rare arthropod is known as Saperion glumaceum. The
species is known from very few  compressed
examples with little to no relief. Saperion
is similar to Kuamaia and Skioldia, but readily distinguished from
them by the lack of marginal spines and a more elongated body outline.
This ventrally preserved example shows some of the appendages.
