Compaginatichnus: a new ichnogenus from Ordovician flysch of eastern Canada

Upper Ordovician flysch of the Matapédia Group of New Brunswick, eastern Canada, contains many examples of burrows that possess an upper meniscate portion and a fecal pellet-packed lower portion. A new ichnogenus, Compaginatichnus, is proposed for these burrows and its type ichnospecies, C. forbesi, is described in detail.
