【 摘 要 】

The Early Devonian Campbellton Formation in northern New Brunswick, Canada, yielded its first eurypterid fossils in 1881. Based on recent taxonomic work, all known specimens have been assigned toPterygotus anglicus , a large pterygotid first described from Scotland. These previously discovered eurypterids are from the western exposure of the Campbellton Formation and are believed to have inhabited a coastal deltaic setting, along with a rich vertebrate assemblage that included cephalaspids, placoderms, acanthodians, and sharks. The single eurypterid abdominal fragment described here as cf.Parahughmilleriawas found in beds near the eastern exposure of the formation from a lacustrine facies. These beds are from classic plant-rich localities of the Camp-bellton Formation and, in addition to plants, have yielded the oldest land-animal assemblage in North America.
