Additions and refinements to Sycodes glabra (Shumard, 1858), a poorly known Late Cretaceous (Campanian) marine gastropod from the northeast Pacific: taxonomic and biostratigraphic implications
Journal: Canadian Journal of Earth Sciences
Publisher: Canadian Science Publishing
Published: 08 July 2014
