A small, irregularly shaped wafer of honey-brown calcite bears a tiny spinose trilobite meraspid -- a "baby" olenellid (probably Olenellus sp.). The semicircular cephalic shield is comparatively large and shows short spines at the general angles. The eyes are large and crescentic. The thorax comprises seven obvious segments, the third bearing lengthy macro pleural spines. Behind the seventh thoracic segment is a vaguely serrated transverse area, but no clear indication of additional segments or the pygidium.
