Abstract

Twenty species of marine invertebrate shells from a gravelly sand deposit close to the present shore at Shippegan, New Brunswick, were identified and shown to be typical of a shallow-water association formed soon after glacial retreat. One specimen yielded a radiocarbon date of 12 600 ± 400 yr. This evidence strengthens previous conclusions on the date of Pleistocene deglaciation and on postglacial sea-level changes in this area.
