Physical manipulation of reindeer teeth, plus the ageing of teeth to determine seasonality of death, were covered in the last annual meeting. It was found that control specimens accurately reflect known age of animal and hence, seasonal occupation by hunters of archaeological sites. Additional information on annular increments of reindeer-caribou and other teeth using sheltered animals on fixed diet will re-open the discussion. This will be followed by interpretation of increment counts of teeth taken from 54 Magdalenian sites, chiefly from S.W. France. Observations of suggested reindeer and hunting band movements 10-15,000 years ago will be discussed.
