Cascada del Pampaterio Level #1 (Pliocene of Argentina)

Also known as Ca.1.75 km downstream from RN3

Where: Buenos Aires, Argentina (38.6° S, 60.6° W: paleocoordinates 38.7° S, 59.8° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Irene Formation, Late/Upper Pliocene (3.6 - 2.6 Ma)

Environment/lithology: terrestrial; massive, sandy siltstone

• The profile exposed in the right margin of the river downstream of the cascade, a cliff 1.5 m high, comprises a lower level of massive dark sandy silts (level #1) cut by a deep layer of coarse gravels (level #2) and covered by a layer of reddish-brown silts with diamicton deposits (level #3). On the left margin, the discontinuously exposed “Irenean” succession is composed of two beds; a lower one of reddish-brown clayey siltstone with carbonate nodules capped by a calcrete layer (level #1), and an upper bed composed of dark brown silts with diamicton deposits and calcrete bodies (level #2).

Size class: macrofossils

Reposited in the MLP
