USNM 4291 (Miocene of Cuba)

Where: Cuba (23.0° N, 82.4° W: paleocoordinates 23.4° N, 78.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Early/Lower Miocene (23.0 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: Unknown lithostratigraphy. AGE: Other collections are assumed to be Early Miocene, based on correlations to Tampa Limeston (Arcadia Formation = Late Oligocene-Early Miocene). Cooke (1919) suggests that this collection may be slightly younger than others, although evidence is inconclusive (Malea camura is found in Middle Miocene-Early Pliocene strata elsewhere in Caribbean). Hence, tentatively assigned to a Middle Miocene age. STRATIGRAPHIC POSITION: Unknown position within local section.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; unlithified siliciclastic sediments

• ENVIRONMENT: Environment not described in text.
• SPECIFIC LITHOLOGY: Unknown lithology, assumed to be siliciclastic. LITHIFICATION: Unlifithied, based on figured specimens.

Size class: macrofossils

Collected by Wren; reposited in the USNM

Collection methods: surface (in situ),

• COLLECTOR: T. H. Wren. REPOSITORY: USNM.
