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 a??Atholville Bedsa?? contain a low diversity ichnofossil assemblage represented by three ichnotaxa: Monomorphichnus , ? Taenidium and Helminthoidichnites . Monomorphichnus is proposed here as being produced by the produced by the activity of the eurypterid Pterygotus anglicus .
