In my view, the suborder Olenellina trilobites are among the most elegant. A product of the Cambrian explosion, the suborder is morphologically diverse and constitutes a major suborder within the order Redlichiida. There are more than 50 genera and subgenera that are an important basis for stratigraphic subdivision in Lower Cambrian rocks. Importantly, members of Olenellina rank among the earliest trilobites in Cambrian statigraphy, dating to about 560 million years ago. Morphologically primitive, its evolutionary origin from Precambrian, segmented worms (if you subscribe to this hypothesis) is evident. Here we have Paedeumias sp. (Walcott described Paedumias transitans from Vermont in 1910). This specimen comes from the Lower Cambrian, Eager formation near Cranbrook, British Columbia, Canada. It has not been described from this locality.

The trilobite has a dark and glossy exoskeloton, about as exquisitely preserved as they can be found, the pix being testiment to the detailed articulation.
