Casa Saman [Saman Fm] (Eocene of Peru)

Where: Piura, Peru (4.8° S, 80.8° W: paleocoordinates 7.3° S, 73.6° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Saman Formation, Late/Upper Eocene (37.2 - 33.9 Ma)

• LITHOSTRATIGRAPHY: From the Saman Fm, which regionally overlies the Restin Fm of the Parinas Gp (Middle Eocene). AGE: Late Eocene (p. 9), on the basis of molluscan biostratigraphy. Foraminifera suggest an upper Eocene age. Olsson states that the Talara and Saman rocks can be referred to the Upper Eocene and in terms of the European section, to the Bartonian and Ludian.....respectively? STRATIGRAPHIC POSITION: From unknown position within formation.

• formation-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, fine-grained, argillaceous sandstone and poorly lithified conglomerate

• Appears to be shelfal siliciclastic environment judging from faunal composition.
• Sandstone and conglomerates, becoming more argillaceous and fine-grained towards the top. Judged to be at best poorly lithified from figured specimens. All specimens have matrix remaining in apertures, suggesting some lithification, but none remain unsegregated from hand specimens or slabs of rock, suggesting that they are somewhat unlithified.

Size class: macrofossils

Collection methods: quarrying,

• No museum repositories are reported, but material my presumably be the AMNH of PRI collections. Because of uncertaintly this field is left ommited.
