Abstract

The Fort Qu'Appelle vertebrate fossil locality is in the Echo Lake Gravel, which lies between tills of the Sutherland and Saskatoon Groups. Biostratigraphers have indicated that the Echo Lake Gravel is either a Sangamonian deposit or a Wisconsin an interstadial deposit. The physical evidence however, suggests that the gravel is an outwash deposit which was deposited at the close of an interglacial or interstadial interval during the advance of the glacier that deposited the Floral Formation.
