S-22, Maria Theresa [Teba Fm] (Cretaceous to of Angola)

Where: Angola (9.3° S, 14.1° E: paleocoordinates 24.0° S, 2.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Teba Formation, Turonian to Turonian (93.9 - 83.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Teba Fm (informal) for which lithostratigraphic relationships are not discussed. AGE: Possibly including Cenomanian-Santonian, on the basis of ammonoid biostratigraphy. Here assigned to Turonian-Santonian to avoid stratigraphic orphaning. STRATIGRAPHIC POSITION: From unknown position within local section.

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified lithology not reported

• ENVIRONMENT: Not stated in text, but presumably shallow marine environment.
• SPECIFIC LITHOLOGY: Not reported in text. LITHIFICATION: Lithified, on the basis of figured specimens and facies description.

Size class: macrofossils

Preservation: cast, mold/impression

Collected by Washburne in 1915; reposited in the AMNH

Collection methods: surface (in situ),

• COLLECTOR: C.W.H. Washburne, about 1915. REPOSITORY: AMNH.
