Pleistocene eider duck ( Somateria cf. mollissima) from Champlain Sea deposits near Shawinigan, Quebec.

Abstract

Most of a pelvic bone of a large eider duck (Somateria cf. mollissima) was collected in place in a unit of stratified clay and sandy silt near Shawinigan, Quebec. Evidently the duck died and was deposited near the northern shore of the Champlain Sea a few hundred years before the sea drained. A sample from a bed of large, marine mollusc shells (Mya arenaria) found in place just above the eider duck fossil yielded a radiocarbon date of 10 300 yr BP. -from Authors
