Where: British Columbia, Canada (53.2° N, 132.0° W: paleocoordinates 22.8° N, 113.0° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Brewericeras huluense ammonoid zone, Haida Formation, Early/Lower Albian (112.0 - 109.0 Ma)
• STRATIGRAPHIC RELATIONS: From the lower sandstone member of the Haida Fm, which rests with apparent unconformity on 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: Presumably near the middle of the local section.
• bed-level stratigraphic resolution
Environment/lithology: coastal; lithified, concretionary, gray, green sandstone
Size class: macrofossils
Preservation: mold/impression
