Geography comments: "along the east bank of the Semliki River"
coordinate estimated from map in Fig. 1
fossils are from "at or near the base of the Katanda beds"
the same level at the laterally equivalent Kt9 was dated at 82 +/- 8 ka (TL on quartz), 155 +/- 38 ka (ESR on teeth), and 140 +/- 4 and 174 +/- 1 ka (U-series on teeth)
