DIRK MEGIRIAN 14 Fig. 7. Inferred extent of the Alcoota LF beds. As discussed in the text, the Woodburne (1967) quarries appear ca 50 m too far west relative to other bone occurrences, especially the gilgais. Woodburnes reference point, Hill 1, is here approximated off an aerial photograph, rather being a feature surveyed in to the Alcoota t.b.m. positional error, which appears to be in the order of ~30-50 m, is possibly due to the plotted position of Hill 1 (Woodburnes (1967) reference point), which was taken off an aerial photo rather than being a surveyed feature. The apparent discrepancy of the relative positions of MAGNT and Woodburne pits is of no major significance in terms of producing a new estimate of the possible extent of the Alcoota LF beds, but it does highlight the merits of continuing with an accurate positional survey of the Alcoota fossil reserve, including the plotting of significant palaeontological, stratigraphic and topographic features. Each worked MAGNT quarry has been equipped with its own benchmark (a steel picket) against which the positions of extracted bones are recorded each year in a field register. The vertical positions of the pit benchmarks are known relative to the Alcoota t.b.m., though their relative horizontal positions have not yet been accurately surveyed. The positional data of bones are currently being transferred to a spreadsheet and analysed by Mr S. Brown (Flinders University). From a casual inspection of the data, it appears that in Main Pit, fossil bone occurs in an interval spanning about 1.4 to 1.9 m (Alcoota t.b.m.), and in the South Pit, to an interval between about 1.2 to 1.7 m. The bones do not occur in a well-bedded sequence, and a sufficiently large area has now been sampled to indicate that the bone beds -1.0 50 m -2 -1 0 1 0 -1 0 -1 N South Pit Main Pit MAGNT test pit MAGNT test pit Woodburne (1965) quarries Approximate extent of surface bone (gilgais) Inferred extent of Alcoota LF beds HILL 1 LEGEND ? ? ? ? ? ? ?
