The trace fossils Arenicolites variabalis Cirauliahnis montanus and Paleodictyon (Glenodictyum) cf. imperfection from the ?Cambro-Ordovician Meguma Group of Nova Scotia are described in detail. The significance of the occurrence of each of these ichnospecies is also noted. The environmental and stratigraphic ranges of A. variabalis are extended respectively to 'deep water' and the Ordovician; the stratigraphic range of C. montanus is extended to the Ordovician and its presence in the Meguma Group to date represents the first and only recording of the species in the western hemisphere; P. cf, irnperfectum provides additional evidence that at least part of the Goldenville Formation is Ordovician.  RESUME On decrit en detail les traces fossiles Arenicolites variabalis, Circulichnis montanus et Paleodiotyon (Glenodictyum) cf, imperfection provenant du groupe Meguma (?Cambro-Ordovicien) de la Nouvelle-Ecosse. De plus, l'on met en evidence la signification de la presence de chacune de ces ichnoespeces. On etend l'environnement d'A. variabilis jusqu'en 'eau profonde' et sa portee stratigraphique jusqu'a l'Ordovicien; la portee stratigraphique de C. montanus est etendue a l'Ordovicien et jusqu'a ce jour, le groupe Meguma repreaente le seul endroit dans l'hemisphere ouest ou sa presence est notee; P. cf. imperfectum fournlt une preuve de plus qu'au moins une partie de la formation de Goldenville date de l'Ordovicien.
