Ogygopsis klotzi is the large, smooth trilobite that paves the Mount Stephen Trilobite Beds above Field, British Columbia, part of the Burgess Shale in Yoho National Park. It is a reference entry only: the beds are protected and no legal specimens are sold. Older museum-exchange specimens exist in institutional collections.
