A late-glacial shell fauna from Point Lepreau, New Brunswick produced a radiocarbon date of 13,500 years B.P. The assemblage contained well-preserved subarctic to boreal molluscs and barnacles typical of late Pleistocene marine deposits from the region. Rare specimens of sea urchin, crab and brittlestar may be the oldest recorded occurrence of these animals in the late-glacial Bay of Fundy. The assemblage fits into a previously defined Zone 3, late-glacial marine invertebrate assemblage in the Bay of Fundy-Gulf of Maine region, characterized as a Diverse Arctic assemblage. RÉSUMÉ La datation par le radiocarbone a situé à 13 500 ans BP une faune invertébéie tardiglaciaire de la pointe Lepreau, ou Nouveau-Brunswick. L'assemblage renferme des mollusques et des bernacles subarctiques à boréaux bien conservés caractéristiques des dépôts marins du Pléistocène tardif de la région. Les spècimens rares d'oursins, de crabes et d'ophiures pourraient constituer les manifestations les plus anciennes de la présence de ces animaux relevées dans la région tardiglaciaire de la baie de Fundy. L'assemblage se situé à l’intérieur de l'assemblage d'invertébrés marins tardiglaciaires de la zone 3 antérieurement défini dans la région de la baie de Fundy et du golfe du Maine, caractérisé en tant qu'assemblage arctique hétéiogene.
