This volume contains two presentations. The first is a transcript of a seminar on Japanese prehistory, which was given in conjunction with (and to provide context for) the exhibit, "50,000 Years of Japanese Prehistory" at the Manitoba Museum of Man and Nature. It has been edited heavily (by G.G. Monks) in places to ensure clarity, eliminate redundancy and improve grammar. The second presentation is a paper on seasonality estimation using bivalve mollusc shells.
