Mid-Cenozoic marine mammals from Alaska. In: L.B. Albright, III (ed.), Papers on geology, vertebrate paleontology, and biostratigraphy in honor of Michael O. Woodburne.

–ABSTRACT: Mid-Cenozoic marine mammals of Alaska were isolated from the Arctic Ocean by Beringia and were thus part of a far North Pacific ecosystem. The amphicynodontid ?Kolponomos, a neocete whale, and a desmostylian were found in the latest Oligocene or earliest Miocene (approximately 23 Ma) Dutch Harbor Member of the Unalaska Formation, Aleutian Chain, Alaska. The Unalaska desmostylian is more derived than Cornwallius but more primitive than Desmostylus. Derived desmostylians are known from the early middle Miocene (16-15 Ma) Bear Lake Formation on the Alaska Peninsula and the Narrow Cape Formation on Kodiak Island. The Miocene Yakatat Formation has produced sparse mammal remains but records the onset of montane glaciation in southern Alaska.
