Copyright © Atlantic Geology, 2007 Nineteenth century collections of Pterygotus anglicus

The Devonian fauna from the Campbellton Formation of northern New Brunswick was discovered in 1881 at the classic locality in Campbellton. About a decade later A.S. Woodward at the British Museum (Natural History) (now the Natural History Museum, London) acquired specimens through fossil dealer R.F. Damon. Woodward was among the first to describe the fish assemblage of ostracoderms, arthrodires, acanthodians and chondrichthyans. At the same time the museum also acquired specimens of a large pterygotid eurypterid. Although the vertebrates received considerable attention, the pterygotids at the Natural History Museum, London are described here for the first time. The first ptery-gotid specimens collected in 1881 by the Geological Survey of Canada were later identified by Clarke and Ruedemann in 1912 as Pterygotus atlanticus, although they suggested it might be a variant of Pterygotus anglicus Agassiz. An almost complete pterygotid recovered in 1994 from the Campbellton Formation at a new locality in Atholville, less than two kilometres west of Campbellton, has been identified as P. anglicus Agassiz. Like the specimens described by Clarke and Ruedemann, the material from the Natural History Museum, London is herein referred to P. anglicus.
