The occurrence of the fern Hausmannia Dunker (Dipteridaceae) in the Cretaceous of Alexander Island, Antarctica

Hausmannia papilio Feruglio is a widespread component of Albian fossil floras on Alexander Island, Antarctic Peninsula. Hausmannia cannot be separated from extant Dipteris and is best regarded as a foliage form genus of the latter. Palaeoecological reconstructions suggests that Hausmannia papilio was a stream-side dweller and pioneer species.
