Rio Maria Farinha - Nautiloidea (Paleocene of Brazil)

Where: Brazil (8.1° S, 34.9° W: paleocoordinates 11.7° S, 21.7° W)

• coordinate based on nearby landmark

• hand sample-level geographic resolution

When: Paleocene (66.0 - 56.0 Ma)

• STRATIGRAPHIC RELATIONS: From unknown lithostratigraphic unit. AGE: Probably Paleocene, according to Miller (1947). Whitfield believed that these beds were Cretaceous in age; Maury proposed that they were early Tertiary in age based on similarities with North American Cimomia and in that no ammonites have been recorded from Brazil. STRATIGRAPHIC POSITION: From unknown position in section.

• bed-level stratigraphic resolution

Environment/lithology: lithified, yellow limestone

• ENVIRONMENT: Not stated, but probably shallow shelf carbonate setting.
• SPECIFIC LITHOLOGY: Yellow earthy limestone. LITHIFICATION: Lithified based on figured specimen.

Size class: macrofossils

Preservation: cast, mold/impression

Collected by White
