Pipas 2 and Pipas 1 (Pleistocene of Angola)

Where: Angola (14.9° S, 12.2° E: paleocoordinates 14.9° S, 12.2° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Middle Pleistocene (0.8 - 0.1 Ma)

• Middle, or, possibly, middle/late, Pleistocene (between ~125,000 (MIS 5e) and ~250,000 yr old)

Environment/lithology: shallow subtidal; gravel and sandstone

• Deposits were formed in a fully marine, rather energetic, nearshore paleoenvironment, with a bathymetric range compatible with the intertidal to upper infralittoral zones. A lower energy, sand-dominated habitat was locally transported and mixed with the gravel-dominated environment, possibly by the action of storms.

•In Pipas 1, the sand lenses appear to dip seaward and wedge out landward. In both deposits the gravel beds are clast-supported and heterolithic, with a diverse composition of quartzite, quartz, granite, porphyritic igneous rocks, limestone, sandstone and other lithic fragments. Possible source rocks for these clasts are nearby basement units

• gravel beds with occasional sand lenses

Size classes: macrofossils, mesofossils
