Abstract

The ichnogenus Bergaueria is formally documented for only the second time from Silurian strata, from the Silurian (prelate Ludlow) of Cape George, Nova Scotia, and for the first time from eastern Canada. Specimens are assigned to B. perata, thus representing the first recording of the ichnospecies in Silurian strata. The excellent preservation of several specimens, combined with are view of previously described examples, permits a revised diagnosis of B.perataut include the common, almost universal, presence of concentric ornamentation. RÉSUMÉ La préscnte documentation formellede l’ichnogenre Bergaueria, dans le Silurien (avant le Ludlow tardif) de Cape George, en Nouvelle-Écosse, est seulement la seconde dans des strates siluriennes et la toute première dans l'Est du Canada. Les spécimens sont rapportés à B. perata, dont la présence au sein de strates siluriennes est de ce fait notée pour la première fois. L'excellente conservation de plusieurs spécimens, combinde à une revision des exemples déjà décrits, permet d'inclure la présence répandue, quasi universelle, d'une ornementation concentrique dans une nouvelle diagnose de B. perata.
