Comments
Innerkip: Vertebrate, invertebrate, and plant fossils were recovered from peat overlain by a detrital sapropel or organic mud. Of five radiocarbon samples, two were from the fossiliferous peat and three from the sapropel. Two finite dates were reported by the Brock Geological Sciences (BGS) laboratory, and three infinite dates were determined by the Geological Survey of Canada (GSC). The implications of the fossil assemblages favour the infinite dates. "Deposition probably occurred at the end of the Sangamon Interglaciation (Isotope Stage 5e) or during warm Early Wisconsinan interstadial (Isotope Stage 5c or 5a)" (Churcher et al., 1990: 299).
