New species of the cyathaspidid Poraspis (Agnatha: Heterostraci) from the Late Silurian and Early Devonian of Northwest Territories, Canada
Four new species of cyathaspidid extend the range of the genus Poraspis back into the Late Silurian and indicate that the Canadian arctic was its center of origin. Poraspis heintzae n. sp., P. cracens n. sp., P. thules n. sp. and P. parmula n. sp. also increase the known geographic range of the genu...
