UCLA Loc. 3789 - Swede Creek [Member III] (Cretaceous of the United States)

Where: Shasta County, California (40.5° N, 122.2° W: paleocoordinates 45.9° N, 86.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Santonian (85.8 - 83.5 Ma)

• LITHOSTRATIGRAPHIC RELATIONS: From an unnamed lithostratigraphic unit; Member III. AGE: Turonian in text; on the basis of ammonite biostratigraphy. STRATIGRAPHIC POSITION: Higher part of Member III according to Popenoe, but doubtful according to author, so possibly from lower part.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified siliciclastic sediments

• ENVIRONMENT: Not reported in text, but apparently shallow marine siliciclastic.
• LITHOLOGY: Not reported, but presumably siliciclastic. LITHIFICATION: Lithified, on the basis of figured specimens.

Size class: macrofossils

Preservation: mold/impression

Collected by Saul in 1954

Collection methods: surface (in situ),

• COLLECTOR: D. Saul, 1954. REPOSITORY: UCLA (at the time).
