Early Devonian fish material from the Horlick Formation, Ohio Range, Antarctica

Some of the oldest (Early Devonian) fossil fish remains from Antarctica found so far are described and include spines of the acanthodian Machaeracanthus sp. and plates of an actinolepid arthrodire. A summary of the finds of Devonian fish from Antarctica recovered so far is provided. Most of them are of Middle or Late Devonian age from Victoria Land. The material reported on here is thus significant in being Early Devonian in age.
