Notes HELMETED MUSKOX (Bootherium bombifrons) FROM NEAR FORT SASKATCHEWAN, ALBERTA: DATING EVIDENCE FOR REDEPOSITION IN LATE PLEISTOCENE ALLUVIUM
ABSTRACT Superimposition and intersection of preglacial and postglacial valley systems on the Canadian plains indicates that some of the recovered Quaternary vertebrate fossils may be redeposited. To test this proposition, an accelerator mass spectrometer (AMS) date was obtained on bone from a previ...
