Loc. A18, Bearskin Bay (A) [Lower Sandstone Mbr, Haida Fm] (Cretaceous of Canada)

Where: British Columbia, Canada (53.3° N, 132.0° W)

• Paleocoordinates: 59.6° N, 91.4° W (Wright 2013)

• 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 3645 ft above base of local section, immediately below shale member.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified, concretionary, gray sandstone

• ENVIRONMENT: not stated in text, but apparently shallow marine siliciclastic.
• SPECIFIC LITHOLOGY: Massive to flaggy, grey, feldspathic sandstone with concretions. LITHIFICATION: Lithified, on the basis of facies description and figured specimens.

Size class: macrofossils

Preservation: mold/impression
