GSC Loc. C-137637 [Shale Mbr, Haida Fm] (Cretaceous of Canada)

Where: British Columbia, Canada (53.0° N, 131.8° W: paleocoordinates 53.4° N, 88.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Sciponoceras gracile ammonoid zone, Haida Formation, Early/Lower Cenomanian (99.6 - 93.5 Ma)

• STRATIGRAPHIC RELATIONS: From the shale member of the Haida Fm, which overlies the sandy member and in turn rests unconformably on the Jurassic Yakoun Fm, and is overlain by the Honna Fm. AGE: Early Cenomanian, on the basis of ammonite biostratigraphy. STRATIGRAPHIC POSITION: From unknown position in local section.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified shale

• ENVIRONMENT: not stated in text, but apparently shallow marine siliciclastic.
• SPECIFIC LITHOLOGY: Shale. LITHIFICATION: Lithified, on the basis of facies description and figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression

Reposited in the GSC

Collection methods: surface (in situ),

• COLLECTOR: Unknown. REPOSITORY: Geological Survey of Canada (GSC).
