As a result of recent field work, the 4000m thick Kimmeridgian-Albian Fossil Bluff Formation of eastern Alexander Island is elevated to Group status (Fossil Bluff Group). Four formations are recognised within the group (which in ascending order are the Ablation Point, Himalia Ridge, Spartan Glacier and Pluto Glacier Formations), characterised by slumped strata, conglomerates, mudstones and sandstones, respectively. Type sections are selected, and representative lithologies and faunas described for each of these stratigraphic units. This succession constitutes probably the best exposed sequence through the Jurassic-Cretaceous boundary at a southern high palaeolatitude.
