Figure 1. Schematic map depicting the spatial orientation of three major landscape facets in the FLK Complex, during Middle Bed I times (1.8 Ma). Landscape reconstructions are based on botanical, sedimentological and paleontological material recovered by OLAPP in the areas of FLK S (Tr. 143, 146, 148), FLK (Tr. 138, 140, 141), FLK N (Tr. 137, 144, 142, 147), and FLK NN (Tr. 134, 135, 145) (Blumenschine et al., in press) and by the M.D. Leakey's (1971) at FLK (Level 22) and FLK NN (Level 1). Birds were recovered from all trenches with the exception of 134, 141, 143 and 148.
