Where: Angola (14.9° S, 12.2° E: paleocoordinates 14.9° S, 12.2° E)
• coordinate stated in text
• local area-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
•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
Size classes: macrofossils, mesofossils
