Ishango - N. Tuf. (Holocene of Congo-Kinshasa)

Also known as ETE Locality 888, Niveaux tufaces, Ishango - N. Tuf.,

Where: Congo-Kinshasa (0.1° S, 29.6° E: paleocoordinates 0.1° S, 29.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Holocene (0.0 - 0.0 Ma)

• Niveaux tufaces. "Wetter climatic conditions can be invoked to explain the appearance of two new and more water-dependent ruminants in the area, kob and African buffalo. Furthermore, if Bagu s arrived in Lake Rutanzige via the Semliki river after the formation of the older deposits, its appearance may perhaps be indicative for a more or less permanent high water level of the river. It may have enabled Bagrus to pass obstacles such as the rapids, which today seem to prevent Lake Rutanzige from being recolonised by fish living in the Lower Semliki and in Lake Mobutu. The foregoing assumptions, combined with the fact that high lake levels and considerable erosional processes took place after the formation of the Ishango horizons, suggest that this second stage may have coincided, at least partially, with the early Holocene wet period."
