A New Pteraspid (Agnatha, Heterostraci) from the Lower Devonian Drake Bay Formation, Prince of Wales Island, Nunavut, Arctic Canada, and Comments on Environmental Preferences of Pteraspids
A new genus and species of pteraspid heterostracan, Mitraspis cracens, gen. et sp. nov., is described from the Early Devonian (Lochkovian) Drake Bay Formation of Prince of Wales Island, Nunavut, Arctic Canada, where it is associated with a rich shallow marine invertebrate fauna. This pteraspid is mo...
