a, Type section of the Dmanisi M5 excavation block. b, Stratigraphic profile of excavation area M6. M6 preserves a larger gully associated with the pipe-gully phase of stratigraphic–geomorphic development in stratum B1. The thickness of the stratum B1 gully fill extends to the basalt surface but includes ‘rip-ups’ of strata A1 and A2, showing that the deposits in stratum B1 post-date those of stratum A. c, Stratigraphic section of excavation area M17. Here, Stratum B1 was deposited after the erosion of stratum A deposits. The stratigraphic position of specimen Dm.5/157–16635 is highlighted with a red diamond. The Masavara basalt is about 50 cm below the base of the profile shown. d, Northern section of block 2. Following the collapse of a pipe and erosion to the basalt, the deeper part of this area was filled with local gully fill of strata B1x, B1y and B1z. Note the uniform burial of all stratum B1 deposits by strata B2, B3 and B4. The sampled specimens are indicated by the five-digit CGG numbers. Extended Data Table 1 provides both the CGG and GNM specimen numbers.
