Bolboparia

Bolboparia is an extinct genus of eodiscinid agnostid trilobites. It lived during the late Lower Cambrian in what today Canada and the United States.
Taxonomy.
"Bolboparia" is most closely related to "Acidiscus" and slightly more distantly to "Stigmadiscus".
Description.
Like all Agnostida, "Bolboparia" is diminutive and the headshield (or cephalon) and tailshield (or pygidium) are of approximately the same size (or isopygous) and outline. Like all Weymouthiidae, "Bolboparia" lacks eyes and rupture lines (or sutures). The short, downsloping glabella and the bulging cheeks give it a very peculiar aspect.
