A single fossil from the Cape Breton, Nova Scotia area was interpreted as a fossil dragonfly larvae and described by Samuel Hubbard Scudder in 1876 as Libellula carbonaria.[1][2] The fossil was very incomplete, consisting of a solitary opisthosoma.[2] With the discovery of more complete fossils from Mazon Creek, Illinois, and Joggins, Nova Scotia, Samuel Scudder redescribed the fossils as amblypygids and moved the species to a new genus, Graeophonus as Graeophonus carbonarius. While describing the British species, Graeophonus anglicus, Reginald Innes Pocock noted significant differences between the Nova Scotian and more complete Mazon Creek fossils.[2] As a result he erected the species Graeophonus scudderi to accommodate the Mazon Creek specimen, and restricted species G. carbonarius to t
