Comments
FaNp-VP, Riddell: Skwara (1988; SkwaraWoolf, 1981) describes the Riddell fauna as a Rancholabrean assemblage that may be as much as 175,000 years old. She rejects S-1305, because it underlies till of the Battleford Formation and leaves too little time for advance and retreat of Late Wisconsinan ice. She notes that GSC-1041, 38,000 +/- 560 BP on wood from the top of the Floral Formation near Kenaston, provides a minimum age for the Riddell fauna. I-8581 is also considered to be anomalously young. The bison bones dated by S-1306 are from a younger context stratigraphically above the Floral Formation.
