There seems to be some possibility that artifacts representative of the Old Copper culture were associated with fossil animals. The evidence is inconclusive but worth noting as a stimulus for future investigations.

In his report on the geology of the Thunder Bay, Ontario, district, Tanton (1931: 83-4) mentions some interesting archaeological remains, information about which was preserved in the files of the Geological Survey of Canada. This information is as follows: in 1918, during industrial excavations, a copper spear point and about 12 mammal bones were found about 40 feet below the surface of the ground in the Kaministikwa Valley at Westfort on the edge of Fort William, Ontario.

The geological section here, according to Tanton (1931: 82) consists of bedrock and conglomerate above which is a “deposit of stratified blue clay between 60 and 90 feet thick, the surface of which has been eroded in channels, and on this uneven surface there are crossbedded sands varying from 4 to 40 feet in thickness filling up the inequalities on the clay surface and forming the plain at the present surface — 638 feet above sea level.”
