Comments | 83 I/01 D.A. St-Onge May 26, 0098 2700 140 Significance : palaeobiology; paleobiologie Associated taxa : Mammalia: Bison sp Aditional Information : GSC-1195, same sample, with only a 1-hour leach in 0.1N NaOH: 2980 +/- 130 BP. GSC-1195-2 had an overnight leach in 0.1N NaOH. Bellis, GaPb-VP: Comment on GSC-1195 (D.A. St-Onge): The bones date a well developed abandoned terrace level (the lower of two) on the northern wall of the North Saskatchewan Valley; the enclosing sediments were deposited when the river floodplain was about 12 m above present river level (cf. St-Onge, 1970, 1972). The date correlates well with both GSC-1205, 10200 160 years (Lowdon and Blake, 1979) on Bison bones in gravel alluvium of a high level (550 m) river terrace at Athabasca which approximates the beginning of postglacial river valley development in this area, and with GSC-1207, 6040 140 (Lowdon and Blake, 1979) on Bison bones from sandy silty alluvium of a middle level river terrace on North Saskatchewan River 7 km upstream from this site; the latter date relates to a phase in the history of North Saskatchewan River when its floodplain was about 20 m above present river level. | |
