Loc. D13, NE shore Maude Island (D) [Lower Sandstone Mbr, Haida Fm] (Cretaceous of Canada)

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 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 upper part 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

Collected by McLearn; reposited in the GSC

• COLLECTOR: F. H. McLearn. REPOSITORY: USGS, presumably now at USNM.
