Abstract

Late Ordovlcian-Early Silurian flysch slope deposits of the Matapedia Group of the Matapedia Basin on the Tobique River, western New Brunswick, Canada, contain 13 ichnogenera (15 ichnospecies), namely:- Chondrites ichnospp.. Cochlichnus anguineus, Dtctyodora scotica, Dictyodora tenuis, Oiaorphichnus ichnosp., Glockerichnus ichnosp., Gordta marina, Helminthopsis ichnosp., Muensteria ichnosp.. Heonereites uniserialis, Nereites jacksoni. Palaeophycus tubularis. Syncoprutus pharmaceus and Yakutatia emersoni. Of these, Oiaorphichnus, Muensteria and Dictyodora have never previously been recorded in the Hatapedia Basin and Dictyodora is recorded for the first time in North America. The total assemblage represents the most diverse ichnocoenosis yet recorded from Paleozoic slope deposits. RÉSUMÉ Sur la rivière Tobique, dans l'ouest du Nouveau-Brunswick, au Canada, les flyschs du Groupe de Hatapedia appartenant au Bassin de Hatapedia, déposés en contexte de talus et d'âge tardiordovlcienàéosilurien. ont livre 13 Ichnogenres (15 ichnoespeces). savoir; Chondrites ichnospp.. Cochlichnus anguineus, Dtctyodora scotica, Dictyodora tenuis, Oiaorphichnus ichnosp., Glockerichnus ichnosp., Gordta marina, Helminthopsis ichnosp., Muensteria ichnosp.. Heonereites uniserialis, Nereites jacksoni. Palaeophycus tubularis. Syncoprutus pharmaceus et Yakutatia emersoni.. Parmi ceux-ci, Dimophichnus, Muensteria et Dictyodora n'ont Jamaisété signales dans le Bassin de Matapedia; 11 sagit. de plus, de la premièr decouverte de Dictyodora en Amèrique du Nord. Au total, l’assemblage représente l’ichnocenose la plus diverse jamais documentée dans les dépôts de talus de Paléozoique. [Traduit par le journal]
