The Upper Devonian gastropod Orecopia in western Canada
£1.00
The distribution of Orecopia is reviewed. Apart from a possible Famennian occurrence in Nevada, the genus as presently known is confined to the Frasnian of western North America and eastern Europe and is represented by five described species. Orecopia mccoyi and O. uchtensis are refigured and a new species, O. cotei, is erected for specimens from British Columbia and the Northwest Territories.It is suggested that the Tathlina Formation of the southern Northwest Territories may be late, rather than middle Frasnian.
