Paleoecology and paleobiogeography of Wenlockian (Silurian) brachiopods of the Cape Phillips Formation from Baillie Hamilton Island, Arctic Canada

Journal of the Czech Geological Society, volume 46 (2001), issue 3-4, 95 - 104

The Baillie Hamilton fauna contains a mixture of both shallow water and deep water brachiopods brought together in debris flows. By using criteria such as taphonomy, abundance distribution, and the community framework concept, a total of 10 communities are recognized from the collection. These communities represent the northern end of the Wenlockian Cordilleran faunal belt. The Baillie Hamilton fauna belongs to the Uralian-Cordilleran Region. The high affinity Index shared by the fauna and the coeval Eastern Great Basin fauna indicates that a gradual environmental gradient separates the Uralian-Cordilleran Region from the North American Province.
