Quadrithyris Zone (Lower Devonian) Near-reef Brachiopods from Bathurst Island, Arctic Canada; with a Description of a New Rhynchonellid Brachiopod Franklinella

A brachiopod fauna from the off-, eef equivalent of the small, reef-knobs in the Stuart Bay Formation of central, eastern Bathurst Island contains a number of species in common with, and readily correlatable with, the Spirigerina fauna (probably Gedinnian) of Royal Creek, Yukon, and the coeval Quadr...

Description
Summary:A brachiopod fauna from the off-, eef equivalent of the small, reef-knobs in the Stuart Bay Formation of central, eastern Bathurst Island contains a number of species in common with, and readily correlatable with, the Spirigerina fauna (probably Gedinnian) of Royal Creek, Yukon, and the coeval Quadrithyris Zone fauna of Nevada. The Spirigerina–Quadrithyris fauna is therefore known to have a north–south range of at least several thousand miles.A new genus and species of rhynchonellid brachiopod, Franklinella pedderi, is described from Spirigerina (= Quadrithyris Zone) beds of Bathurst Island and Royal Creek, Yukon. This species appears to be ancestral to the genus Thliborhynchia Lenz.
