Punta San Andres (Pliocene of Argentina)

Where: Buenos Aires, Argentina (38.2° S, 57.7° W: paleocoordinates 38.2° S, 56.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

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

• Level 2, San Andres Formation, Marplatan Age/Stage, Sanandresian Subage/Substage

Environment/lithology: cave; red, sandy claystone and carbonate

• "Level 2 is characterized by orange to reddish sandy to clayey sediments (with a greater proportion of pelitic materials compared with the preceding level). A paleosol is evident in the middle of this interval. This paleosol is overlain by lattice-type calcareous concretions that become conspicuously more concentrated towards the top, forming a thick compact layer that stands out from the profile. Another palaeosol is present at the top of this level."
