Bergaueria perata Prantl, 1945 from the Silurian of Cape George, Nova Scotia

Abstract

The ichnogenus Bergaueria is formally documented for only the second time from Silurian strata, from the Silurian (pre-late 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 a review of previously described examples, permits a revised diagnosis of B. perata to include the common, almost universal, presence of concentric ornamentation. -Author
