The Albian ammonite Aioloceras Whitehouse in Antarctica

Abstract

The first record of the Albian ammonite Aioloceras is documented from the Kotick Point Formation, James Ross Island, northern Antarctic Peninsula. The material is identified with the type species, Aioloceras argentinum (Bonarelli, 1921), previously only known from southern Patagonia. It is associated with Desmoceras sp., Anagaudryceras sp., Parasilesites sp., Rossalites sp. and Phyllopachyceras sp. On the basis of this assemblage, the presence of the Aioloceras argentinum Assemblage Zone from Patagonia, which is considered coeval to the upper lower Albian Mammillatum Superzone, is extended to Antarctica.
