Ichnology of the Devonian (Emsian) Campbellton Formation, New Brunswick, Canada

[摘要] The Campbellton Formation has long been known to yield a fossil assemblage of Devonian (Emsian) fish and eurypterids at its westernmost exposure near Campbellton and Atholville, and a well described flora and early land animal fauna toward its easternmost exposure near Dalhousie Junction. Although the body fossil assemblage (paleobotany, vertebrate and invertebrate paleontology), paleoecology and paleoenvironmental context of the formation have been extensively studied, ichnofossils are rare and have not been described previously. Fossils from the vertebrate and eurypterid bearing ‘Atholville Beds’ contain a low diversity ichnofossil assemblage represented by three ichnotaxa: Monomorphichnus , ? TaenidiumandHelminthoidichnites .Monomorphichnusis proposed here as being produced by the produced by the activity of the eurypteridPterygotus anglicus .
