Cañada Honda, Maracaibo (Eocene of Venezuela)

Where: Venezuela (10.7° N, 71.6° W: paleocoordinates 8.2° N, 64.2° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Pauji Formation, Bartonian (41.3 - 38.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Las Flores Fm, correlative with the upper part of the Pauji Formation in the correlation chart of Sutton (1946). The Pauji Formation appears to be the name used in the Maracaibo Basin now. AGE: In the Río San Pedro Section, nannofossils indicate an undifferentiated Middle Eocene age (NP15-NP16; Lutetian) for the base of the Pauji Formation. Planktonic foraminifera are characteristic of the late Middle Eocene Truncorotaloides Zone (Walton, 1966 in L.E.V., 1999). According to Medina (2008), On the basis of Turborotalia cerroazulensis and Truncorotaloides rohri a Middle Eocene Age (Zones P11/P14 of Bolli & Saunders 1985 - mid-Lutetian to mid-Bartonian) has been determined. STRATIGRAPHIC POSITION: From thin sandstone bed in unknown part of formation.

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, ferruginous sandstone

• ENVIRONMENT: The Paují Formation, up to 1200 m thick, is dominated by mudstone and shale, with minor sandstones, encompassing a wide variety of depositional settings, ranging from foreshore to slope and in water depths perhaps reaching up to 500 m (González de Juana et al.,1980). Overall, integration of sedimentological and palaeontological datasets indicates a deepening trend through the deposition of the Paují Formation (González de Juana et al., 1980). Without more lithological information, the fossil could be from almost any environment.
• LITHOLOGY: Ferruginous sandstone. LITHIFICATION: Lithified, on the basis of figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression

Collected by Sutton, Furnish; reposited in the PRI, SUI, UCMP

Collection methods: surface (in situ),

• COLLECTORS: Possibly Sutton, ~ early 1940's. REPOSITORY: State University of Iowa; University of California.
