A new fossil Euspira? (Mollusca: Gastropoda: Naticidae) from the Gubik Formation on the North Slope of Arctic Alaska
A new naticid gastropod, Euspira? louiemarincovichi n. sp., is described from the Pliocene to Pleistocene age Gubik Formation on the North Slope of Alaska between Skull Cliff in the west and the Kogru River/Teshekpuk Lake area in the east. It is easily distinguished from all other Atlantic, Pacific...
