A Paleoenvironmental Analysis Based on Ostracode Assemblages from the Late Pliocene Tuapaktushak and Middle Pleistocene Karmuk Members of the Gubik Formation of the Arctic Coastal ...

This study records and analyzes ostracode assemblages recovered from sediments assigned to the Late Pliocene Tuapaktushak and Middle Pleistocene Karmuk members of the Gubik Formation in the Skull Cliff area of the Arctic Coastal Plain in western Alaska. Forty-three species were identified from 47 sa...
