Description

Bristolia is an extinct genus of trilobite, fossil marine arthropods, with eight or more small to average size species. It is common in and limited to the Lower Cambrian (Upper Olenellus-zone) shelf deposits across the southwestern US, which constitutes part of the former paleocontinent of Laurentia.
