Where: British Columbia, Canada (53.3° N, 132.0° W: paleocoordinates 22.9° N, 110.8° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Haida Formation, Albian (113.0 - 100.5 Ma)
• STRATIGRAPHIC RELATIONS: From the lower sandstone member of the Haida Fm, which rests unconformably on massive agglomerate of the Jurassic Yakoun Fm, and is overlain by the shale member, which passes up into the Honna Fm. AGE: Albian, on the basis of ammonite biostratigraphy. STRATIGRAPHIC POSITION: From 1010-1070 m above base of local section, at top of sandstone member.

Preservation: mold/impression
Collected by Jones in 1963; reposited in the USNM
