Abstract

The trace fossil Neonereites multiserialis Pickerill and Harland is recorded and described from the Lower Devonian Wapske Formation of northwest New Brunswick. Preserved typically in positive hyporelief on sandstone soles, the ichnospecies can potentially be confused with morphologically similar ichnotaxa, particularly Granularia Pomel, Ophiomorpha Lundgren, Ardelia Chamberlain and Baer and Edaphichnium Bown and Kraus, and is best differentiated by undertaking, whenever possible, vertical transverse and longitudinal sectioning of the structures. The records and included proposed synonymy suggest that Neonereites multiserialis is Silurian (Wenlock) to Tertiary (Eocene) in age and is indicative of deep-water flysch environments. RÉSUMÉ La Formation de Wapske (Dévonien inférieur, nord-ouest du Nouveau-Brunswick) a livré l'échnite Neonereites multiserialis Pickerill et Harland, dont on fournit ici une description. Il est parfois delicat de distinguer cette ichnoespèce, typiquement conservée en demi-relief convexe à la base des bancs de grès, de formes voisines (notamment Granularia Pomel, Ophiomorpha Lundgren, Ardelia Chamberlain et Baer, Edaphichnium Bown et Kraus). L'étude du materiel par coupes longitudinales et transversales constitue, le cas échéant. la meilleure approche afin de tranchcr la question. La documentation fossile et la synonymie que l’on propose suggérent que Neonereites multiserialis s'échelonne du Silurien (Wenlock) au Tertiaire (Eocene) et fait foi de milieux d'eau profonde, sièges d'une sédimentation à caractère flyschoide.
