Harington August 21, 0098 1975 120 Significance : palaeobiology; paleobiologie Associated taxa : Mammalia: Ursus maritimus PfLt-VP: This is the only find of polar bear bones, other than at modern sea level or near an archaelogical site, in 3 field sessions of extensive ground traversing on Prince of Wales Island. The bones looked old and are worth dating on the speculation that the bear died on the beach or on sea ice. Polar bear canines were still in their sockets, but bone was not well preserved. Several other bones were scattered about an area of 100 metre radius; these were not collected. A preliminary emergence curve for this part of Prince of Wales Island places relative sea level at >64 metres at 8.5 ka BP. Driftwood from 58.5 metres was dated to 8230 +/- 110 (GSC-3936); bowhead rib at 58 metres was dated 8875 +/- 135 (S-2588); bowhead rib at 66 metres was dated 9605 +/- 140 (S-2590). Deglaciation of the site occurred around 11,000 BP. | |
