Résumé

The discovery of a Zoophycos-group trace fossil questionably attributed to Echinospira is reported from the Middle Pennsylvanian Sydney Mines Formation of Nova Scotia. Zoophycos-group trace fossils are composed of a central axis from which helicoidally arranged sheets of spreite emanate, giving the appearance of stacked cones. Such traces are commonly reported from marine paleoenvironments throughout the Phanerozoic. This occurrence, the first of its kind in the Maritimes Basin, provides further evidence for marine influence during the deposition of these dominantly terrestrial coal-bearing successions. RÉSUMÉ On signale la découverte d’un ichnofossile du groupe Zoophycos rattaché de façon douteuse à Échinospira dans la formation du Pennsylvanien moyen de Sydney Mines, en Nouvelle-Écosse. Les ichnofossiles du groupe Zoophycos sont constitués d’un axe central duquel émanent des feuilles de spréite disposées de façon héliocoïdale leur conférant l’aspect de cônes étagés. Ces ichnofossiles sont communément signalés dans les paléoenvironnements marins du Phanérozoïque. La présence de cet ichnofossile particulier, premier du genre dans le bassin des Maritimes, fournit une autre preuve de l’influence marine pendant la sédimentation de ces successions carbonifères en prédominance terrestres.
