Note on Pterygotus anglicus Agasslz (Eurypterida: Devonian) from the Campbellton Formation, New Brunswick

Abstract

Fragments of the large eurypterid Pterygotus, recently collected from the Devonian Campbellton Formation at Atholville, New Brunswick, are identified as belonging to P. anglicus Agassiz. The only previous Pterygotus specimens from this site, collected in 1881, were assigned to a new species P. atlanticus Clarke and Ruedemann, in 1912. Clarkc and Ruedemann's suggestion that P. atlanticus might turn out to be a small specimen of P. anglicus is supported by this new find. However, possible revision of P. atlanticus awaits the discovery of additional, more complete, material.
