BdCx-5, Reid: This is a stratified prehistoric shell heap attributed to the Micmac. Clarke and Erskine note that the status of Littorina littorea and of Ceprea hortensis as indigenous to the Western Hemisphere was previously doubted. The presence of caribou bones, and crowded lines of growth in Mercenaria mercenaria, provide evidence that the climate was formerly colder than at present. It was considered on archaeological grounds that the site would have been occupied for not less than a century between AD 1200 and 1500.
