Extract

Previously described faunas of Early Silurian through Late Pennsylvanian age from the Alexander terrane have been endemic, or have variously suggested North American or Asiatic affinities, leaving the paleogeographic history of the terrane uncertain although indicating a location closer to North America than to Asia (Armstrong, 1970; Douglass, 1971; Savage, 1981, 1985, 1989; Savage et al., 1978; Savage and Barkeley, 1985; Soja, 1988; Vaskey, 1982). The occurrence reported here of the Canadian Arctic brachiopods Nanukidium cf. N. cunninghamensis and Atrypoidea scheii in the Alexander terrane during the Late Silurian could be additional evidence supporting the view that the Alexander terrane was not far removed from the North American craton during middle Paleozoic time.
