GSC 7591a, Loc. D8, NE shore Maude Island (D) (Cretaceous of Canada)

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

• ENVIRONMENT: not stated in text, but apparently shallow marine siliciclastic.
• SPECIFIC LITHOLOGY: Grey and greenish, feldspathic sandstone, occasionally concretionary. LITHIFICATION: Lithified, on the basis of facies description and figured specimens.

Size class: macrofossils

Preservation: mold/impression
